Poor Jerome Littlefield (Jerry Lewis). He wants to be a doctor but that's not exactly the perfect career choice when you're hopelessly squeamish. So he settles for the job of orderly at the Whitestone Sanitarium, a career move that's guaranteed to keep the patients and viewers in stitches! The fun begins with Sammy Davis, Jr.'s rendition of the film's title song and continues as the bumbling Jerome, a one-man disaster area, triggers chaos every time he tries to lend a helping hand. From causing the patients more trauma to a highspeed ambulance chase, Lewis and his healthy dose of comic mishaps are the perfect prescription for all that ails you.
