The Stooge are separate characters in this short. Larry is a womanizer who is having an affair with Moe's wife. At the same time, he is also making eyes at Joe's fiancée, Millie (Angela Stevens), as well. Moe, however, tracks down the conniving Larry at his pet shop, and gives him the works before Larry calms him down. Realizing he needs to cover his tracks, Larry looks for a "fall guy" in the form of Joe. Larry then gets Joe a job as an underwear salesman and the first place he goes is Moe's home. While Joe is modeling his ware, Larry lies to Moe about Joe's advances on Millie. Both of them go storming over to Moe's, while Joe flees up the chimney. After making a quiet getaway, Joe bumps into Larry, and turns him in.

- Triple Crossed is a reworking of the previous short film that follow the same storyline; He Cooked His Goose which had featured Shemp Howard as the third stooge.
- When Moe shoots at Joe up the chimney, you can hear Shemp Howard's yell from He Cooked His Goose. In a cost-saving measure, Joe Besser's voice was not dubbed over Shemp's for authenticity. In addition, when Larry is walking in the hallway from the elevator to meet Moe's wife, Joe is hiding in the closet wearing a Santa Claus outfit; however, it is Shemp who is whistling at Larry. Also, Shemp's face can be seen in the background peeking from underneath the bearskin rug and can be seen when he opens the janitor closet door and slams Moe.
