Humor Risk

Harpo played the hero, a detective named Watson who made his entrance in a high hat, sliding down a coal chute into the basement. Groucho played an old movie villain, who sported a long moustache and was clad in black, while Chico was probably his chuckling [Italian] henchman. Zeppo portrayed a playboy who was the owner of a nightclub in which most of the action took place, including a cabaret, [which allowed] the inclusion of a dance number. The final shot showed Groucho in ball and chain, trudging slowly off into the gloaming. Harpo, in a rare moment of romantic glory, gets the girl in the end.
