HE COOKED HIS GOOSE (1952)

Larry is a pet dealer who's seeing Moe's wife while at the same time trying to steal Shemp's fiancée. When Moe becomes suspicious, Larry attempts to frame Shemp as the boyfriend. He gets Shemp a job as a door-to-door pajama salesman and sends him to Moe's apartment, and then tells both Moe and Shemp's fiancée to go there and catch him in the act. Larry's plan backfires when Shemp catches him and lets Moe deliver some punishment.
