A band plays the theme song until a ball-bearing salesman named Norman appears and closes a door on them. He introduces himself as the hero of the piece, and walks down a corridor filled with doors, explaining that each of them has a different one of his problems behind it.

Norman enters a door, which takes him to his boss's office. Their company is trying to get a man named Fanshawe to buy a large consignment of ball-bearings. The boss has discovered Fanshawe is an alcoholic, so he orders Norman to take Fanshawe to a bar, get him drunk, and persuade him to sign. Norman objects on moral grounds. During the argument, the two become children, with the boss demanding that Norman bully a fellow child in order to get into the boss's gang. The two revert to adults, and the boss tries reverse psychology, wondering out loud if Norman is really suitable for the job. Norman seemingly caves in, but on exiting the office, he vows not to do what is being asked of him, and to simply ask Fanshawe to sign the contract if he thinks the ball-bearings are good enough.

He then enters another door, containing his father. Norman asks his father questions about what is right and wrong, but his father merely gives Norman vague psychobabble and stories from his childhood and young adulthood. He then tells Norman that the key to success is not to make waves, and to fit in.

Walking through another door, Norman is taken to a party. A man named Leo wears a lampshade on his head and walks around repeating "Approval?" A drunken salesman congratulates Norman for closing the deal with Fanshawe, and tells a joke which involves a traveling salesman mistaking an Eskimo woman for a walrus. The audience does not hear most of the joke, as Norman talks over it and tells the drunken man that he should not be telling jokes that disparage another race or minority group. Norman walks over to the bar and Hal the bartender, who is also drunk, asks if he wants more to drink. Norman tells Hal that he has had enough to drink and asks for a ginger ale. Hal taunts him, accusing Norman of hating himself when he is drunk.

Back in the corridor, Norman apologizes for the display, and re-opens the door containing the band. Both the band and Norman are revealed to be inside the head of another, larger version of Norman, visible through a door. The larger Norman closes the door on his head.
