Fed up with their jobs, Fred and Barney secretly plan to buy a drive-in restaurant, but then Fred has to deal with a suspicious Wilma, who wants to know why two young girls (carhops seeking jobs) are calling for him, and what the messages regarding two tons of dino-burger meat mean. This episode contains the song “Burger on a Bun (The Car Hop Song),” sung by two waitresses; when they phone Fred at home, he humorously tells Wilma that they’re “Charlie” and “Irving.” Later Fred and Barney are publicly embarrassed when Wilma and Betty sing the car hop song in public and warn their husbands that they haven’t forgiven them for deceiving them! Ginny Tyler voices one of the carhops while Nancy Wible voices the other.
