You're Never Too Young

“Dino's the singing dean of a girl's school, Jerry - a wolf in kid's clothing - in a class by himself with 503 coeds.”

A valuable diamond has gone missing, and the one person holding it is Wilbur Hoolick (Jerry Lewis), an aspiring barber who never meant to be part of the theft. To stay out of reach of the man hunting for it, he passes himself off as a 12-year-old. Norman Taurog builds the comedy on a simple notion: a grown man can hide inside a child's life, and everyone around him sees only what they expect.
