W.C. Fields stars in a remake of his silent comedy So's Your Old Man. Fields plays Sam Bisbee, an erstwhile inventor who is the laughingstock of his small town.
Returning in defeat from a disastrous big-city demonstration of his latest invention, Sam makes the acquaintance of a beautiful young woman (Adrienne Ames) who happens to be an incognito foreign princess. After Bisbee tells her of how he'd like to be a success for the sake of his family, the princess decides to use her celebrity to Sam's benefit.
She arrives in his town and lets it be known of her high regard for the downtrodden Bisbee. Suddenly Sam is the town's big shot, enabling him to merchandise his inventions and do right by his wife and daughter.
Sam earns the respect he's so long deserved--but he's never completely convinced that the princess is who she claims to be, and keeps congratulating her on her racket. Based on a story by Julian Street, You're Telling Me is climaxed by a sidesplitting recreation of W.C. Fields' Ziegfeld Follies golf routine.
