Calvin and Hobbes

Calvin and Hobbes is a daily comic strip that was written and illustrated by American cartoonist Bill Watterson, and syndicated from November 18, 1985, to December 31, 1995. It follows the humorous antics of Calvin, a precocious and adventurous six-year-old boy, and Hobbes, his sardonic stuffed tiger. The pair are named after John Calvin, a 16th-century French Reformation theologian, and Thomas Hobbes, a 17th-century English political philosopher. At the height of its popularity, Calvin and Hobbes was featured in over 2,400 newspapers worldwide; as of January 2010, reruns of the strip still appear in more than 50 countries. Nearly 45 million copies of the 18 Calvin and Hobbes books have been sold.

Calvin and Hobbes is set in the contemporary United States in an unspecified suburban area. The strip depicts Calvin's flights of fantasy and his friendship with Hobbes, and also examines Calvin's relationships with family and classmates. Hobbes' dual nature is a defining motif for the strip: To Calvin, Hobbes is a live anthropomorphic tiger; all the other characters see him as an inanimate stuffed toy. Though the series does not mention specific political figures or current events, it does explore broad issues like environmentalism, public education, philosophical quandaries, and the flaws of opinion polls.

History
Calvin and Hobbes was conceived when Bill Watterson, working in an advertising job he detested, began devoting his spare time to cartooning, his true love. He explored various strip ideas but all were rejected by the syndicates. United Feature Syndicate finally responded positively to one strip, which featured a side character (the main character's little brother) who had a stuffed tiger. Told that these characters were the strongest, Watterson began a new strip centered on them. Though United Feature rejected the new strip, Universal Press Syndicate eventually took it.

The first strip was published on November 18, 1985, and the series quickly became a hit. Within a year of syndication, the strip was published in roughly 250 newspapers. Before long the strip was in wide circulation outside the United States. By April 1, 1987, Watterson and his work were featured in an article in The Los Angeles Times. Calvin and Hobbes twice earned Watterson the Reuben Award from the National Cartoonists Society in the Outstanding Cartoonist of the Year category, first in 1986 and again in 1988. He was nominated again in 1992. The Society awarded him the Humor Comic Strip Award for 1988. Calvin and Hobbes has also won several more awards.

Watterson took two extended breaks from writing new strips, from May 6, 1991, to February 1, 1992, and from April 4 through December 31, 1994. In 1995, Watterson sent a letter via his syndicate to all editors whose newspapers carried his strip:

The 3,150th and final strip ran on Sunday, December 31, 1995. It depicted Calvin and Hobbes outside in freshly fallen snow, reveling in the wonder and excitement of the winter scene. "It's a magical world, Hobbes, ol' buddy... Let's go exploring!" Calvin exclaims as they zoom off over the snowy hills on their sled, leaving, according to one critic ten years later, "a hole in the comics page that no strip has been able to fill."

Syndication and formatting
From the outset, Watterson found himself at odds with the syndicate, which urged him to begin merchandising the characters and touring the country to promote the first collections of comic strips. Watterson refused. To him, the integrity of the strip and its artist would be undermined by commercialization, which he saw as a major negative influence in the world of cartoon art.

Watterson also grew increasingly frustrated by the gradual shrinking of available space for comics in the newspapers. He lamented that without space for anything more than simple dialogue or sparse artwork, comics as an art form were becoming dilute, bland, and unoriginal. Watterson strove for a full-page version of his strip, in contrast to the few cells allocated for most strips. He longed for the artistic freedom allotted to classic strips such as Little Nemo and Krazy Kat, and he gave a sample of what could be accomplished with such liberty in the opening pages of the Sunday strip compilation, The Calvin and Hobbes Lazy Sunday Book.

During Watterson's first sabbatical from the strip, Universal Press Syndicate continued to charge newspapers full price to re-run old Calvin and Hobbes strips. Few editors approved of the move, but the strip was so popular that they had little choice but to continue to run it for fear that competing newspapers might pick it up and draw its fans away.

Upon Watterson's return, Universal Press announced that Watterson had decided to sell his Sunday strip as an unbreakable half of a newspaper or tabloid page. Many editors and even a few cartoonists criticized him for what they perceived as arrogance and an unwillingness to abide by the normal practices of the cartoon business. Watterson had negotiated the deal to allow himself more creative freedom in the Sunday comics:

I took a sabbatical after resolving a long and emotionally draining fight to prevent Calvin and Hobbes from being merchandised. Looking for a way to rekindle my enthusiasm for the duration of a new contract term, I proposed a redesigned Sunday format that would permit more panel flexibility. To my surprise and delight, Universal responded with an offer to market the strip as an unbreakable half page (more space than I'd dared to ask for), despite the expected resistance of editors.

To this day, my syndicate assures me that some editors liked the new format, appreciated the difference, and were happy to run the larger strip, but I think it's fair to say that this was not the most common reaction. The syndicate had warned me to prepare for numerous cancellations of the Sunday feature, but after a few weeks of dealing with howling, purple-faced editors, the syndicate suggested that papers could reduce the strip to the size tabloid newspapers used for their smaller sheets of paper. ... I focused on the bright side: I had complete freedom of design and there were virtually no cancellations.

For all the yelling and screaming by outraged editors, I remain convinced that the larger Sunday strip gave newspapers a better product and made the comics section more fun for readers. Comics are a visual medium. A strip with a lot of drawing can be exciting and add some variety. Proud as I am that I was able to draw a larger strip, I don't expect to see it happen again any time soon. In the newspaper business, space is money, and I suspect most editors would still say that the difference is not worth the cost. Sadly, the situation is a vicious circle: because there's no room for better artwork, the comics are simply drawn; because they're simply drawn, why should they have more room?

Animation
Watterson did consider allowing Calvin and Hobbes to be animated, and has expressed admiration for the art form of animation. In a 1989 interview in The Comics Journal he said:

After this he was asked if it was "a bit scary to think of hearing Calvin's voice." He responded that it was "very scary," and that although he loved the visual possibilities of animation, the thought of casting voice actors to play his characters was uncomfortable. He was also unsure whether he wanted to work with an animation team, as he had done all previous work by himself. Ultimately, Calvin and Hobbes was never made into an animated series. Watterson later stated in the Calvin and Hobbes Tenth Anniversary Book that he liked the fact that his strip was a "low-tech, one-man operation," and took great pride in the fact that he drew every line and wrote every word on his own.

Merchandising
Bill Watterson insists that cartoon strips should stand on their own as an art form, and has resisted the use of Calvin and Hobbes in merchandising of any sort. Watterson explained in a 2005 press release:

Almost no legitimate Calvin and Hobbes merchandise exists outside of the book collections. Exceptions produced during the strip's original run include two 16-month calendars (1988–1989 and 1989–1990), and the textbook Teaching with Calvin and Hobbes, which has been described as "perhaps the most difficult piece of official Calvin and Hobbes memorabilia to find."

On July 16, 2010 the United States Postal Service released a set of postage stamps honoring five comic strips, one of them Calvin and Hobbes.

Uclick, the digital division of Andrews McMeel Universal, offers licensed prints of Calvin and Hobbes strips through its website.

The strip's immense popularity has led to the appearance of various counterfeit items such as window decals and T-shirts that often feature crude humor, binge drinking and other themes that are not found in Watterson's work. Images from one strip in which Calvin and Hobbes dance to loud music at night were commonly used for copyright violations. After threat of a lawsuit alleging infringement of copyright and trademark, some sticker makers replaced Calvin with a different boy, while other makers made no changes. Watterson wryly commented, "I clearly miscalculated how popular it would be to show Calvin urinating on a Ford logo."

Style and influences
Precedents to Calvin's fantasy world can be found in Crockett Johnson's Barnaby, Charles M. Schulz's Peanuts, Percy Crosby's Skippy, Berkeley Breathed's Bloom County, and George Herriman's Krazy Kat, while Watterson's use of comics as sociopolitical commentary reaches back to Walt Kelly's Pogo and Quino's Mafalda. Schulz and Kelly particularly influenced Watterson's outlook on comics during his formative years.

In early strips, the drawings have a flatter, Peanuts-like look but show more depth in later strips. Notable elements of Watterson's artistic style are his characters' diverse and often exaggerated expressions (particularly those of Calvin), elaborate and bizarre backgrounds for Calvin's flights of imagination, expressions of motion, and frequent visual jokes and metaphors. In the later years of the strip, with more panel space available for his use, Watterson experimented more freely with different panel layouts, art styles, stories without dialogue, and greater use of whitespace. He also makes a point of not showing certain things explicitly: the "Noodle Incident" and the children's book Hamster Huey and the Gooey Kablooie are left to the reader's imagination, where Watterson was sure they would be "more outrageous" than he could portray.

Watterson's technique started with minimalist pencil sketches drawn with a light pencil (though the larger Sunday strips often required more elaborate work); he then would use a small sable brush and India ink on Strathmore bristol board to complete most of the remaining drawing. He lettered dialogue with a Rapidograph fountain pen, and he used a crowquill pen for odds and ends. He used Liquid Paper to correct mistakes. He was careful in his use of color, often spending a great deal of time in choosing the right colors to employ for the weekly Sunday strip. When Calvin and Hobbes began there were 64 colors available for the Sunday strips. For the later Sunday strips Watterson had 125 colors as well as the ability to fade the colors into each other.

Art and academia
Watterson used the strip to poke fun at the art world, principally through Calvin's unconventional creations of snowmen but also through other expressions of childhood art. When Miss Wormwood complains that he is wasting class time drawing impossible things (a Stegosaurus in a rocket ship, for example), Calvin proclaims himself "on the cutting edge of the avant-garde." He begins exploring the medium of snow when a warm day melts his snowman. His next sculpture "speaks to the horror of our own mortality, inviting the viewer to contemplate the evanescence of life." In further strips, Calvin's creative instincts diversify to include sidewalk drawings (or, as he terms them, examples of "suburban postmodernism").

Watterson also lampooned the academic world. In one example, Calvin writes a "revisionist autobiography," recruiting Hobbes to take pictures of him doing stereotypical kid activities like playing sports in order to make him seem more well-adjusted. In another strip, he carefully crafts an "artist's statement," claiming that such essays convey more messages than artworks themselves ever do (Hobbes blandly notes, "You misspelled Weltanschauung"). He indulges in what Watterson calls "pop psychobabble" to justify his destructive rampages and shift blame to his parents, citing "toxic codependency." In one instance, he pens a book report based on the theory that the purpose of academic writing is to "inflate weak ideas, obscure poor reasoning, and inhibit clarity," titled The Dynamics of Interbeing and Monological Imperatives in Dick and Jane: A Study in Psychic Transrelational Gender Modes. Displaying his creation to Hobbes, he remarks, "Academia, here I come!" Watterson explains that he adapted this jargon (and similar examples from several other strips) from an actual book of art criticism.

Overall, Watterson's satirical essays serve to attack both sides, criticizing both the commercial mainstream and the artists who are supposed to be "outside" it. Not long after he began drawing his "Dinosaurs in Rocket Ships" series, Calvin tells Hobbes:

The strip for Sunday, June 21, 1992 criticized the naming of The Big Bang as not evocative of the wonders behind it, and coined "Horrendous Space Kablooie", an alternative that achieved some informal popularity among scientists and was often shortened to "the HSK." The term has also been referenced in newspapers, books, and university courses.

Calvin
Calvin, named after the 16th-century theologian John Calvin, is a six-year-old, whose last name is never mentioned in the strip. Despite his poor grades in school, Calvin demonstrates his intelligence through his sophisticated vocabulary and a philosophical mind:

He commonly wears his distinctive red-and-black striped shirt, black pants, and white-and-magenta sneakers. He also wears a jacket when going to school or when playing in the snow. He is an enthusiastic reader of comic books and has a tendency to order items marketed in comic books or on boxes of his favorite cereal, Chocolate Frosted Sugar Bombs. Watterson described Calvin:

Calvin also has a sensitive side as well. This is displayed, for example, when he finds a dying raccoon and tries to save it but fails. The scene is made even more poignant by Calvin asking Hobbes not to "go anywhere" whilst Hobbes hugs him and promises him he won't.

Hobbes
From the other characters' perspectives, Hobbes is Calvin's stuffed tiger. From Calvin's point of view, Hobbes is an anthropomorphic tiger, much larger than Calvin and full of independent attitudes and ideas. When the perspective shifts to any other character, readers again see merely a stuffed animal, usually seated at an off-kilter angle and blankly staring into space. Watterson explains:

In more than one strip, Hobbes is shown being washed in a washing machine, a fact Hobbes takes in stride and which Watterson has referred to as "one of the stranger blurrings of what Hobbes is."

Hobbes is named after the 17th-century philosopher Thomas Hobbes, who held what Watterson describes as "a dim view of human nature." Hobbes (the tiger) is much more rational and aware of consequences than Calvin, but seldom interferes with Calvin's troublemaking beyond a few oblique warnings. Hobbes is sarcastic when Calvin is being hypocritical about things he dislikes.

Although the debut strip shows Calvin capturing Hobbes by means of a snare (with a tuna sandwich as the bait), a later comic (August 1, 1989) indicates that Hobbes has been with Calvin since Calvin was a baby:

Watterson eventually decided that it was not important to establish how Calvin and Hobbes met.

Calvin's parents
Calvin's unnamed mother and father are typical middle-class parents. Like many other characters in the strip, their relatively down-to-earth and sensible attitudes serve as a foil for Calvin's outlandish behavior.

Watterson says some fans were angered by the way Calvin's parents thought of Calvin. This is shown by the fact that Calvin's father claimed that he wanted a dachshund instead of Calvin, and often tries to "deny" that Calvin is his biological son:

Calvin's parents are not above some outrageous behavior of their own. For example, Calvin asks for a cigarette and his mother gives him one to teach him a lesson. Calvin's father tells Calvin sarcastic lies when asked a straight question, and Calvin often believes them:

Watterson defends what Calvin's parents do, remarking that in the case of parenting a kid like Calvin, "I think they do a better job than I would." Calvin's father is overly concerned with "character building" activities in a number of strips, either in the things he makes Calvin do or in the masochistic eccentricities of his own lifestyle. For example, Calvin's father is shown coming home from an early morning run in the snow, which he follows with a bowl of plain oatmeal.

Calvin's father is a patent attorney (like Watterson's own father) and his mother is a stay-at-home mom. Both remain unnamed except as "Mom" and "Dad," or pet names such as "honey" and "dear" between themselves. Watterson says, "As far as the strip is concerned, they are important only as Calvin's mom and dad." Calvin's Uncle Max was in the strip for a week but could not refer to the parents by name, which was one of the main reasons Max never reappeared.

Susie Derkins
Susie Derkins, the only important character with both a first and last name, is a classmate of Calvin's who lives on his street. Named for the pet beagle of Watterson's wife's family, she appeared early in the strip as a new student in Calvin's class. She is polite and studious, and likes to play house or host tea parties with her stuffed animals. However, she is also depicted playing imaginary games with Calvin in which she is a high-powered lawyer or politician and he is her househusband. Though both of them hate to admit it, Calvin and Susie have quite a bit in common. For example, Susie is shown on occasion with a stuffed bunny rabbit named "Mr. Bun." Susie also has a mischievous (and sometimes aggressive) streak, which can be seen when she subverts Calvin's attempts to cheat on school tests by feeding him incorrect answers, or clobbers Calvin when he attacks her with snowballs. Susie also regularly bests Calvin in confrontations such as their water balloon and snowball fights, employing guile or force. Hobbes often openly expresses romantic feelings for Susie, much to Calvin's disgust. Calvin starts a "club" (of which he and Hobbes are the only members) that he calls G.R.O.S.S. (Get Rid Of Slimy GirlS), and while holding "meetings" in Calvin's treehouse or in the "box of secrecy" in Calvin's room, they usually come up with some way to annoy or socially maim Susie, most of which backfire on them completely. In one instance, Calvin steals one of Susie's dolls for ransom, only to have Susie retaliate by nabbing Hobbes. Watterson admits that Calvin and Susie have a nascent crush on each other, and that Susie is inspired by the type of woman whom Watterson himself found attractive and eventually married.

Secondary characters
Calvin also interacts with a handful of secondary characters. These include his babysitter, the school bully, his school teacher and the school principal.

Rosalyn
Rosalyn is Calvin's babysitter. She takes advantage of his parents' desperation to leave the house and the fact that no one else will babysit for Calvin by demanding advances and raises. In her final appearance in the strip, she at last forces Calvin to behave by using his own haphazard rules against him during a game of Calvinball. She is also probably the only character in the strip whom Calvin really fears, as she does not mince words or actions to get Calvin to behave or go to bed on time. Watterson put her in a Sunday strip early on, never thinking of her as a regular character. But Rosalyn's intimidation of Calvin surprised Watterson, so she came back several times. At one point she was Calvin's swimming instructor, though he was only shown to attend one lesson.

Moe
Moe is, according to Calvin, a "six-year-old who shaves" and a stereotypical bully who picks on Calvin (both physically and emotionally) and calls him names. Moe is the only regular character whose speech is shown in an unusual font as his frequently monosyllabic dialogue is shown in crude, lower-case letters. Watterson describes Moe as "every jerk I've ever known."

Miss Wormwood
Miss Wormwood is Calvin's world-weary teacher, named after the junior devil in C. S. Lewis' The Screwtape Letters. She usually wears either a polka-dotted dress or a brown dress, and is another character who serves as a foil to Calvin's mischief. Calvin, when in his Spaceman Spiff persona, sees Miss Wormwood as a slimy, often dictatorial alien. Calvin refers to Miss Wormwood's indigestion ("It's really gross how she drinks Maalox straight from the bottle"), her medication ("I wonder if her doctor knows she mixes all those prescriptions") and her smoking habit ("Rumor has it she's up to two packs a day, unfiltered"). Miss Wormwood reacts to Calvin's behavior by tightly shutting her eyes and thinking "Five years until retirement" repeatedly. Watterson describes her as "an unhappy person" due to her belief in the value of education.

Mr. Spittle
Mr. Spittle is the school principal to whose office Miss Wormwood threatens to send Calvin for his pranks for spanking. Infrequently, Susie also accompanies Calvin to the principal's office. Though his name has only been shown in one story, he has appeared many times including the first story about Calvin's duplicator.

Uncle Max
Uncle Max is Calvin's paternal uncle. Uncle Max was originally meant as a character who could increase the possibilities of the strip: as Watterson noted, "Calvin could go visit Uncle Max...". However, Watterson dropped the character, after finding it was awkward that Max could not address Calvin's parents by name and realizing that Max was redundant as far as the strip's personality goes.

Recurring elements
There are many recurring gags in the strip, some in "reality" and others in Calvin's imagination. These are as follows:

Calvin's roles
Calvin imagines himself as a great many things, including dinosaurs, elephants, jungle-farers and superheroes. Three of his alter egos are well-defined and recurrent:


 * "Spaceman Spiff" is a heroic spacefarer who narrates his experiences in the third person. As Spiff, Calvin battles aliens (typically his parents or teacher, but also sometimes other kids his age) with a ray gun known as a "zorcher" (later "frap-ray blaster", "death ray blaster" or "atomic napalm neutralizer") and travels to distant planets (his house, school, or neighborhood), often crashing unhurt on a planet. Calvin's self-narration as Spaceman Spiff is frequently riddled with alliteration: "Zounds! Zorched by Zarches, Spaceman Spiff's crippled craft crashes on planet Plootarg!"


 * "Tracer Bullet," a hardboiled private eye, says he has eight slugs in him ("One's lead, and the rest are bourbon."). In one story, Bullet is called to a case in which a "pushy dame" (Calvin's mother) accuses him of destroying an expensive lamp (broken during an indoor football game between Calvin and Hobbes). Later, he is snatched by the pushy dame's "hired goon" (Calvin's father having a talk with him). He made his debut when Calvin donned a fedora to hide a haircut Hobbes had given him. These strips are drawn in elaborate, shadowy black-and-white that evoke film noir. Watterson did not attempt Tracer Bullet stories often, due the time-consuming way the strip needed to be drawn and inked.


 * As "Stupendous Man" he pictures himself as a superhero in disguise, wearing a mask and a cape made by his mother, and narrating his own adventures. While in character as Stupendous Man, he refers to his alter ego as a mild-mannered millionaire playboy. Stupendous Man almost always "suffers defeat" at the hands of his opponent. When Hobbes asks if Stupendous Man has ever won any battles, Calvin says all his battles are "moral victories." Stupendous Man's nemeses include "Mom-Lady" (Calvin's mom), "Annoying Girl" (Susie Derkins), "Crab Teacher" (Miss Wormwood), and "Baby-Sitter Girl" (Rosalyn). Some of the "super powers" of the villains have been revealed: Mom-Lady has a "mind scrambling eyeball ray" that wills the victim to "do her nefarious bidding," and Baby Sitter Girl has a similar power of using a "psycho beam" which weakens "Stupendous Man's stupendous will". The "powers" of Annoying Girl and Crab Teacher are unknown. Calvin often tries to pretend he and "Stupendous Man" are two different people, but it never seems to work. Stupendous Man has multiple "superpowers", including, but not limited to, super strength, the ability to fly, various vision powers (such as "high-speed vision") and a stomach of steel.

Cardboard boxes
Calvin has had several adventures involving corrugated cardboard boxes, which he adapts for many different uses. In one strip, during which Calvin shows off his Transmogrifier, a device that transforms its user into any desired shape, Hobbes remarks, "It's amazing what they do with corrugated cardboard these days." Calvin is able to change the function of the boxes by rewriting the label and flipping the box onto another side. In this way, a cardboard box can be used not only for its conventional purposes (a storage container for water balloons, for example), but also as a flying time machine, a duplicator or, with the attachment of a few wires and a colander, a "Cerebral Enhance-o-tron." In addition, Calvin uses a cardboard box as a desk when he is attempting to sell things. Often, Calvin's merchandise is something that no one would want, such as "suicide drink," "a swift kick in the butt" for one dollar, insurance, or "frank appraisal of your looks" for fifty cents. In one strip, he sells "happiness" for ten cents, which was a water balloon in the face, revealing that Calvin meant his own happiness. In another strip, he sold "insurance", firing a slingshot at those who refused. In some strips, he attempted to sell "great ideas". The box has also functioned as a secret meeting place for G.R.O.S.S., as the "Box of Secrecy".

Calvinball
"Other kids' games are all such a bore!

They've gotta have rules and they gotta keep score!

Calvinball is better by far!

It's never the same! It's always bizarre!

You don't need a team or a referee!

''You know that it's great, 'cause it's named after me! ''"

- Part of the Calvinball theme song

Calvinball is a game played by Calvin and Hobbes as a rebellion against organized team sports; according to Hobbes, "No sport is less organized than Calvinball!" Calvinball was first introduced to the readers at the end of a 1990 storyline involving Calvin reluctantly joining recess baseball. It quickly became a staple of the comic afterwards.

The only hint at the true creation of the game ironically comes from the last Calvinball strip, in which a game of football quickly devolves into a game of Calvinball. Calvin remarks that "sooner or later, all our games turn into Calvinball," suggesting a similar scenario that directly led to the creation of the sport. Calvin and Hobbes usually play by themselves, although in one storyline Rosalyn (Calvin's baby-sitter) plays in return for Calvin doing his homework, and plays very well once she realizes that the rules are made up on the spot.

The only consistent rule states that Calvinball may never be played with the same rules twice. Scoring is also arbitrary, with Hobbes at times reporting scores of "Q to 12" and "oogy to boogy". The only recognizable sports Calvinball resembles are the ones it emulates (i.e., a cross between croquet, polo, badminton, capture the flag, and volleyball.) Equipment includes a volleyball (the eponymous "Calvinball"), a croquet set, a badminton set, assorted flags, bags, signs, a hobby horse, and enigmatic and never-pictured "time-fracture wickets". Other things appear as needed, such as a bucket of ice-cold water, a water balloon, and various songs and poetry. Players also wear masks resembling blindfolds with holes for the eyes. When Rosalyn asks Calvin the reason for the requirement, Calvin responds, "Sorry, no one's allowed to question the masks." When asked how to play, Watterson states, "It's pretty simple: you make up the rules as you go." Calvinball is a nomic or self-modifying game, a contest of wits and creativity rather than stamina or athletic skill, in which Hobbes (and on one occasion, Rosalyn) usually outwits Calvin, who takes it in stride, in contrast to his otherwise poor sportsmanship.

Snow sculptures
Calvin often creates horrendous/dark humor scenes with his snowmen. He uses the snowman for social commentary, revenge, or pure enjoyment. Examples include Snowman Calvin being yelled at by Snowman Dad to shovel the snow; Snowman A eating snowcones taken from Snowman B, who is lying on the ground with an ice-cream scoop in his back; a snowman house of horror; and snowmen representing the people he hates. "The ones I really hate are small, so they'll [melt] faster," he says. There was even a time he accidentally brought a snowman to life and it made itself and a small army into "deranged mutant killer monster snow goons."

Calvin's snow art is often used as a commentary on art in general. For example, Calvin has complained more than once about the lack of originality in other people's snow art and compared it with his own grotesque snow sculptures. In one of these instances, Calvin and Hobbes claim to be the sole guardians of high culture; in another, Hobbes admires Calvin's willingness to put artistic integrity above marketability, causing Calvin to reconsider and make an ordinary snowman.

Wagon and sled
Calvin and Hobbes frequently ride downhill in a wagon, sled, or toboggan, depending on the season, as a device to add some physical comedy to the strip and because, according to Watterson, "it's a lot more interesting ... than talking heads." While the ride is sometimes the focus of the strip, it also frequently serves as a counterpoint or visual metaphor while Calvin ponders the meaning of life, death, God, philosophy or a variety of other weighty subjects. Many of their rides end in spectacular crashes which leave them battered and broken, a fact which convinces Hobbes to sometimes hop off before a ride even begins. In the final strip, Calvin and Hobbes depart on their toboggan to go exploring. This theme is similar (perhaps even homage to) scenarios in Walt Kelly's Pogo.

G.R.O.S.S.
G.R.O.S.S., which stands for Get Rid Of Slimy GirlS, is a club which consists of only two members: Calvin and Hobbes. The club was founded in the garage of their house. To clear space for its activities, Calvin and (purportedly) Hobbes push Calvin's parents' car, causing it to roll into a ditch (but not suffer damage); the incident necessitates changing the club's location to Calvin's treehouse. They hold meetings to attempt to annoy Susie Derkins. Notable actions include planting a fake secret tape near her in attempt to draw her in to a trap, trapping her in a closet at their house, and creating elaborate water balloon traps. Calvin gave himself and Hobbes important positions in the club, Calvin being "Dictator-for-Life" and Hobbes being "President-and-First-Tiger". They go into Calvin's treehouse for their club meetings and often get into fights during them. The password to get into the treehouse is intentionally long and difficult, which has on at least one occasion ruined Calvin's plans. (Because Hobbes can climb the tree without the rope, he got to think up the password, which heaps praise upon tigers.) An example of this can be seen in the comic strip where Calvin, rushing to get into the treehouse to throw things at a passing Susie Derkins, insults Hobbes, who is in the treehouse and thus has to let down the rope. Hobbes forces Calvin to say the password for insulting him. By the time Susie arrives, in time to hear Calvin saying some of the password, causing him to stumble, Calvin is on "Verse Seven: Tigers are perfect/the E-pit-o-me/of good looks and grace/and quiet..uh..um..dignity". The opportunity having passed to pelt Susie with something, Calvin threatens to turn Hobbes into a rug.

Books
There are 18 Calvin and Hobbes books, published from 1987 to 2005. These include 11 collections, which form a complete archive of the newspaper strips, except for a single daily strip from November 28, 1985. (The collections do contain a strip for this date, but it is not the same strip that appeared in some newspapers. Treasuries usually combine the two preceding collections with bonus material and include color reprints of Sunday comics.)

Watterson included some new material in the treasuries. In The Essential Calvin and Hobbes, which includes cartoons from the collections Calvin and Hobbes and Something Under the Bed Is Drooling, the back cover features a scene of a giant Calvin rampaging through a town. The scene is based on Watterson's home town of Chagrin Falls, Ohio, and Calvin is holding the Chagrin Falls Popcorn Shop, an iconic candy and ice cream shop overlooking the town's namesake falls. Several of the treasuries incorporate additional poetry; The Indispensable Calvin and Hobbes book features a set of poems, ranging from just a few lines to an entire page, that cover topics such as Calvin's mother's "hindsight" and exploring the woods. In The Essential Calvin and Hobbes, Watterson presents a long poem explaining a knight's battle against a monster from Calvin's perspective.

A complete collection of Calvin and Hobbes strips, in three hardcover volumes totaling 1440 pages, was released on October 4, 2005, by Andrews McMeel Publishing. It includes color prints of the art used on paperback covers, the treasuries' extra illustrated stories and poems, and a new introduction by Bill Watterson in which he talks about his inspirations and his story leading up to the publication of the strip. The alternate 1985 strip is still omitted, and two other strips (January 7, 1987, and November 25, 1988) have altered dialogue. A four-volume paperback version was released November 13, 2012.

To celebrate the release (which coincided with the strip's 20th anniversary and the tenth anniversary of its absence from newspapers), Calvin and Hobbes reruns were made available to newspapers from Sunday, September 4, 2005, through Saturday, December 31, 2005, and Bill Watterson answered 15 questions submitted by readers.

Early books were printed in smaller format in black and white. These were later reproduced in twos in color in the "Treasuries" (Essential, Authoritative, and Indispensable), except for the contents of Attack of the Deranged Mutant Killer Monster Snow Goons. Those Sunday strips were not reprinted in color until the Complete collection was finally published in 2005. Every book since Snow Goons has been printed in a larger format with Sundays in color and weekday and Sunday strips larger than they appeared in most newspapers.

Watterson claims he named the books the "Essential, Authoritative, and Indispensable" because, as he says in The Calvin and Hobbes Tenth Anniversary Book, the books are "obviously none of these things".

Teaching with Calvin and Hobbes
An officially licensed children's textbook entitled Teaching with Calvin and Hobbes was published in a single print-run in 1993. The book, which has been "highly recommend[ed]" as a teaching resource, includes five complete Calvin and Hobbes multi-strip story arcs together with lessons and questions to follow, such as:

The book is rare and sought by collectors.

Academic response
In her book When Toys Come Alive, Lois Rostow Kuznets says that Hobbes serves both as a figure of Calvin's childish fantasy life and as an outlet for the expression of libidinous desires more associated with adults. Kuznets also looks at Calvin's other fantasies, suggesting that they are a second tier of fantasies utilized in places like school where transitional objects such as Hobbes would not be socially acceptable. Another academic critic, Philip Sandifer, using the psychoanalytic theories of Jacques Lacan, identifies the strip's depiction of time within Calvin's real and imaginary worlds as a manifestation of the Lacanian concepts of the Imaginary, the Real, and the Symbolic.

A collection of original Sunday strips was exhibited at Ohio State University's Billy Ireland Cartoon Library & Museum in 2001. Watterson himself selected the strips and provided his own commentary for the exhibition catalog, which was later published by AndrewsMcMeel as Calvin and Hobbes Sunday Pages 1985–1995.

Since the discontinuation of Calvin and Hobbes, individual strips have been licensed for reprint in schoolbooks, including the Christian homeschooling book The Fallacy Detective in 2002, and the university-level philosophy reader Open Questions: Readings for Critical Thinking and Writing in 2005; in the latter, the ethical views of Watterson and his characters Calvin and Hobbes are discussed in relation to the views of professional philosophers.

Academics and intellectuals were interviewed for a September 9, 2009 BBC Radio 4 half-hour documentary about the comic strip, narrated by Phill Jupitus.

Paleontologist and paleoartist Gregory S. Paul praised Bill Watterson for the scientific accuracy of the dinosaurs appearing in Calvin & Hobbes.
