In the year of "One Billion, Trillion B.C.", Porky Pig gets a magazine in the mail. While he is reading it, he finds out that bearskins are all the rage, so he sets out to kill a bear. He goes into the forest, finds a bear, and attempts to kill it to get the bearskin.
The magazine was called "Expire", another take on "Esquire" magazine. The cartoon Brother Brat would also feature another parody of the magazine.
