Happy Days
Howard feels that Joanie has been seeing too much of Chachi lately, so he offers her her own phone if she agrees not to see Chachi for two weeks. Joanie and Chachi sneak off to a concert in Chicago and have to stay in the same room, the honeymoon suite, at a motel because it is the only one left.

Despite Howard's objection, Joanie decides to buy a car because she and Chachi are tired of having to double-date, and Chachi cannot afford to buy his own.
On Christmas Eve, a terrible blizzard traps Howard and Joanie at the hardware store and Fonzie, Potsie, Chachi, Jenny, and Roger at Arnold's.

Meanwhile, Arnold's has a new cook, but Fonzie's sixth sense tells him that something isn't right about him.

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.
Because she's never been to his house or met his mother, Joanie thinks that Chachi is ashamed of her. Fonzie invites the Cunninghams over to the Arcola's for dinner on Chachi's behalf. Fonzie surmizes that Chachi is embarrassed of his mother and uncle and of the fact that they're poor.

Chachi discovers a great basketball player who recently transferred to Jefferson High. However, he initially holds back when performing for Roger and, suddenly, changes his mind about being on the team when his father orders him home in the middle of a practice.
Desperate to get Chachi on the school's basketball team, a scout for Eastern Florida University offers him a scholarship and several other superfluous perks - including a cheerleading scholarship for Joanie. Fonzie is extremely excited for Chachi, but Howard and Roger think the scholarships are too good to be true.
