We take a tour of Porky's Poppa's farm, to the tune of Old MacDonald. After meeting several animals, "on this farm, he has a mortgage" which he frets over, particularly since Bessie has stopped producing milk. Poppa orders an Acme milk producing robot, and the beast vs. machine battle is on.

While at the Crocadero night club, Porky dreams of becoming a bandleader, but he finds out that he has no money. Instead he gets a job at the club working on the dishes. His boss gets the wrong idea of Porky involving a fly and fires him. The boss's bandleaders don't show up, so he brings Porky back and has him impersonate several famous bandleaders.
