Potsie is staying with the Cunninghams, and he and Richie sneak out to watch a drag race in which Fonzie is involved.

Fonzie announces that he's getting married and brings his bride-to-be to the Cunningham house for dinner. There, Howard recognizes her as stripper he saw at a hardware convention in Chicago.

With Howard's hardware store about to face new competition, the Cunninghams decide they need to rent the room above their garage to generate extra income. Howard is shocked when Richie rents it to Fonzie.

With Richie in a dating slump, Fonzie sets Richie and himself up on a double date with two of his girls, Laverne and Shirley.
