Plot

Moe, a struggling boxing manager, has a lunchtime confrontation with three of his fighters, who are angry that he has not paid them and threaten to abandon him. The disgruntled fighters begin physically bullying their timid waiter, Curly. A serendipitous turn of events unfolds when strolling violinist Larry plays the melody of "Pop Goes the Weasel". The tune triggers a violent outburst from Curly, who becomes hyperanimated and effortlessly knocks out all three fighters. When Curly recovers his composure, he explains to Moe that "every time I hear that 'weasel' tune, something pops inside of me." Moe recruits Curly as a boxer and hires Larry to play the tune ringside so Curly can easily defeat his opponents and win them prize money.
