Chicago Reader review:
One of the stranger chapters in Jerry Lewis's continuing psycho-biography, the most direct and intimidating confrontation between his perpetual preadolescent character and the wide world of sex. Jerry bungles into a plot line that might have been lifted from an ancient stag movie: he's the handyman at a women's boardinghouse. But Jerry resists the fleshy temptations of the opposite sex with all the blind determination of a six-year-old. An interesting, if not screamingly funny, film (1961), enlivened by some of Lewis's most audacious camera work and a spectacular three-story cutaway set that impressed Godard so much he borrowed it for Tout va Bien.
Here (and above) is the trailer.
