Porky's Pastry Pirates is a 1942 cartoon directed by Friz Freleng.
Porky owns a bakery. A fly looks inside, and is quite hungry at what he sees. A bee arrives, and tells him to go for it. The bee comes in and annoys Porky to the point where he tries to swat the fly, but instead the Bee electrifies the flyswatter. The bee then try's to teach the fly how to disguise itself as a bee. However it backfires when the costume he's wearing falls off and Porky manages to nab him. The bee itself returns hoping to find food but instead the fly is there. He hits the bee with a swatter.
