The Prize Pest is a 1950 Warner Bros. Looney Tunes cartoon featuring Porky Pig and Daffy Duck. It was directed by Robert McKimson, and written by Tedd Pierce. It was originally released December 22, 1951.
This is considered by some to be one of the last screwball Daffy Duck cartoon, as all of the directors eventually stuck with the greedy, self-centered Daffy that emerged in Rabbit Fire (1951).
This cartoon was included in the 1988 movie compilation Daffy Duck’s Quackbusters in which Daffy hired Porky in his “Paranormalist at Large” company. The cartoon was shortened in the movie, with a mix of new animation. Daffy reprises his “crazy” look from this short in the Looney Tunes Show episode “Devil Dog” when trying to distract some SWAT team guys.
After listening to one of his favourite radio programs, Porky Pig receives a grand prize from the station. Out of the gift box pops Daffy Duck, who insists on living in Porky’s house. After numerous attempts to throw Daffy out of the house, Daffy devises a plan to stay. He tells Porky that he has a split personality (á la The Strange Case of Doctor Jekyll and Mr. Hyde) When people treat him badly, he turns into a hideous monster, which he does by messing his hair up and putting in fangs, whereas when treated with kindness he becomes sweet and cuddly.
When Porky realises he’s been had (after coming out scared from a closet with a skeleton in it, presumably put in there by Daffy), he now has to outsmart this psychotic duck and get him out of the house by dressing up as a monster.
When Daffy sees the monster, he becomes so scared, he falls apart (literally) and runs out of the house screaming (putting himself back in the gift box in the process). When Porky accidentally sees himself in the mirror in his monster costume (which he stated that only a craven little coward would be scared of), he scares himself so much that he jumps onto a chandelier (“So I’m a craven little coward”).
