Who's Minding the Store? is a 1963 American comedy film directed by Frank Tashlin and starring Jerry Lewis, Jill St. John, Agnes Moorehead, Ray Walston, Kathleen Freeman, and John McGiver.^[2] It was released on November 28, 1963, by Paramount Pictures.

Rich Mrs. Phoebe Tuttle is upset that her daughter Barbara is engaged to a man beneath their social status, Norman Phiffier. Barbara has been keeping her heiress status to the Tuttle Department Store fortune a secret from Phiffier, knowing he is a proud person who refuses to marry her until he can afford to buy her a home.

Phiffier, a dog walker, is as awkward socially as he is physically. Mrs. Tuttle despises Phiffier but arranges for him to get a job at one of her stores. She directs the store manager, Quimby, to assign Phiffier a series of impossible and outrageous tasks, hoping he will become frustrated and quit, proving to her daughter that he is worthless. Instead, even though he suffers a series of hilarious mishaps, Phiffier becomes more driven and determined, and Quimby realizes that "he's a man of character". Phiffier also meets and befriends John Tuttle, Phoebe's henpecked husband, with neither suspecting each other's identity.

After a final spectacular failure involving a super-strong vacuum cleaner and a dog trapped inside it, Barbara's identity as an heiress is revealed. Disappointed by the Tuttles' deception, Phiffier breaks off the engagement and quits, returning to his previous job as dog walker. In this way he finally proves his worth to Mrs. Tuttle and, after she, John and Barbara temporarily join the dog-walking service to deliver their apologies to Phiffier, he and the Tuttles reconcile.
