The show opens with the Ricardos and the Mertzes sitting around the Ricardos' piano, singing songs together. After the Mertzes leave, Lucy and Ricky wind up in an argument: Lucy wants to leave the bedroom window open, while Ricky wants it closed. The Mertzes, who are trying to get some sleep, are most irritated by the noise. They angrily phone the Ricardos and demand that they cut down on the racket. This, as you can imagine, leads to a big quarrel between the Ricardos and the Mertzes. Lucy and Ricky decide that they can't take it anymore, and they want to move out. However, there is a slight problem--they've signed a lease. The Ricardos thus decide to become the most undesirable tenants ever so that they can break that lease. They succeed in doing so, but ultimately decide that they can't move away and that they must apologize to their friends.

A shy young teenager named Peggy has a major crush on Ricky. Ricky, however, is tired of all this "attention" that this girl is giving him, so asks Lucy to have a talk with her. During their conversation, Lucy asks Peggy to think of some other boys her own age that she might like to go out with instead. Peggy, it seems, also likes a boy named Arthur Morton. Unfortunately, Arthur is painfully shy and cannot dance, so Lucy volunteers to give him a dance lesson. But it is then that Arthur becomes infatuated with Lucy! To get the two off their backs, Lucy and Ricky come up with a solution: they will dress up and act like 90 year olds, and scare their "young fans" back to reality.
