This frantic comedy finds Raymond (Jerry Lewis) working in a department store. Mr. Tuttle (John McGiver) is the watchful owner, whose outspoken wife Phoebe (Agnes Moorehead) makes no secret about her feelings that Raymond is an incompetent boob. Barbara (Jill St. John) is the pretty elevator operator, and unknown to Raymond, the boss' daughter.
Quimby (Ray Walston) is the floor manager who has more of an eye for the ladies than his job at the store. Raymond proceeds to wreck every department in the store, earning new positions with each mishap. Two of the many sight gags are when Raymond is sent to paint the top of a flagpole and a hilarious vacuum cleaner demonstration that naturally goes awry.
