This is a great Jerry Lewis vehicle. Lewis stars as a TV repairman who's the long lost son of a rich man who recently passed away. Greedy relatives attempt to do him in, so they can collect on the inheritance. There's more plot (even if it is a cliche and a mere framework for Lewis' comedy) than in most of Jerry Lewis' films, and his antics have seldom been funnier.

The film was directed by Frank Tashlin, who was a former comic artist and Looney Tunes director. He brings those sensibilities to this film, which has all the flavor of a zany cartoon.
