Porky & Daffy
Porky & Daffy is a 1938 Warner Bros. cartoon produced by Leon Schlesinger.
It all starts at the home of Daffy & Porky. Porky's relationship with Daffy is strained, as he is a lazy sloth. Porky has found an ad inviting all comers to take on a wrestling rooster named The Champ. Porky has trouble waking Daffy up, but eventually does so by clanging a dinner platter over his head. This causes him to immediately go crazy and start warming up for a wrestling match.
Later, at a jam-packed wrestling ring, Porky volunteers Daffy to fight th
e Champ after all the other fighters run off scared. Despite the fact that he blows off Daffy's XXX sacks of flour (which he used to make himself look more muscular) and acts like a lion, Daffy is unfazed and simply retaliates by acting like a lion tamer, driving him back with a chair and whip. After the pelican announcer's longwinded introductions, the fight begins. (Daffy: "Sold- to the American Tobacco Company!")
In Round 1, the announcer reminds them "no hitting below the belt", so Daffy raises his shorts to cover all but his head. The Champ then blows his shorts off. Daffy flees, but with a reminder from Porky, gets on his "tricycle", wheeling through midair, and soon going so fast that the slower Champ cannot keep up, using the advantage to repeatedly punch him. Once he is out of sight, the announcer and the Champ look around for Daffy, only to discover he has hidden inside the pelican's beak. The Champ beats up the announcer to get to Daffy, finally catching him.
He knocks him out, and Porky is forced to rush back to their home to get the dinner platter and wake him up again before ten-count. Daffy awakens in his frenzy again, and begins ferociously attacking the Champ without regard to his situation, ducking all of his blows eventually knocking him out. The announcer counts to ten, and Daffy wins. Daffy wakes him up by clanging the platter, and he goes into a frenzy much like Daffy did. Iris out.
The cartoon is also available as a bonus feature on the Angels with Dirty Faces DVD.
The idea of an outside power turning someone into a crazy but skilled fighter has been also seen in several Three Stooges shorts, all involving Curly Howard. The most famous is from Punch Drunks, when Curly would go fighting mad whenever he heard Pop Goes the Weasel, and Moe using this to turn him into a boxing champ. A similar idea would be used in Grips, Grunts, and Groans when the smell of Wild Hyacinth would make Curly even able to beat up professional wrestlers.
