It's a Joke, Son! is a 1947 American comedy film directed by Benjamin Stoloff (in his final directorial role in a film) featuring radio comedian Kenny Delmar as Senator Beauregard Claghorn, a character on Fred Allen's radio program and later the inspiration for the cartoon character Foghorn Leghorn. The film was the first American production for Eagle-Lion Films and although it was produced on a very small budget compared to other Hollywood films, it was a box-office disappointment; one theater chain removed the film after less than a week after it only drew $1,000 in ticket sales.

The film contributed to a multimillion-dollar loss for Eagle-Lion in 1947, and Arthur B. Krim later stated that the studio had overpaid for Delmar and overestimated his bankability. It is in the public domain.
