After Jenny's date dumps her before a big masquerade ball, Fonzie agrees to take her. They dress as a bride and groom and, as part of a talent portion of the party, have a make-believe wedding. However, since the captain of the boat performed the ceremony, the marriage may be legal. Roger believes they can get the marriage annulled if Jenny agrees to it, but, instead, she comes into Fonzie's apartment carrying suitcases.

Jealous of Joanie's friendship with a new girl in school, Mikki, Jenny spreads a false rumor that Mikki is pregnant. As the rumor circulates, Fonzie is added to it as being the child's father.
