Mickey's Surprise Party

Mickey's Surprise Party is a short that debuted in 1939 at the New York World's Fair as a promotional short for Nabisco. Since then, it has often been edited to suit the snack products in question.

Synopsis
Minnie's biscuits are spoiled when she accidentally gets unpopped popcorn into the dough, and the whole batch explodes. ("It always happened to my mother, too," Mickey helpfully comments.) Luckily, Mickey had biscuits from the store with him all along.

Trivia

 * This is one of the few Disney cartoons in the public domain.
 * When this short was released on the 1998 VHS The Spirit of Mickey, the Nabisco snacks were edited to be generic-appearing snack foods, and the audio when Mickey arrives with the snacks has been re-dubbed.
 * Walt Disney hated the idea of public commercials for some reason, and swore he would not do one until then.
 * This is the one of three Mickey Mouse cartoons (the other two being Minnie's Yoo Hoo and The Mad Doctor), and one of only a few Disney cartoons in general to be in the public domain, and is freely distributed across online video websites such as YouTube.
 * The cartoon was shown at the 1939 New York World's Fair.
 * This is notable for being the first Disney commercial sponsoring a company.
 * This is the first cartoon with Mickey and Minnie to use their current designs.
