I'm from the City

Joe Penner is a champion trick rider at the circus. But only when manager Richard Lane hypnotizes him with a fossilized Egyptian acorn. Kathryn Sheldon offers Lane a thousand dollars if Penner will ride in an annual race, which gives Penner a chance to court Lorraine Krueger, Lane her sister, Kay Sutton, and for Lafe McKee to believe that Penner is his long-lost son. There's also Paul Guilfoyle as an Indian and Clarence Nash as a duck.

Penner was a comic who came from the burlesque stage. His catchphrase, "Wanna buy a duck?" somehow catapulted him into a nationwide craze and a radio show. RKO, in one of its fits of remembering that the 'R' stood for Radio, tried him out and produced several movies like this until his untimely death in 1941. They averaged pretty much like this, demonstrating Penner as a decent mechanical comic with decent timing and a limited bag of tricks.
