Vivian: (from outside) Hey, Fonzie! It's me, Vivian.
Howard: What was that?
Marion: That's Vivian, dear.
Howard: Well, I heard that.
Richie: A date tonight, Fonz?
Fonzie: A maybe date.
Vivian: Fonzie, are you coming out?
Fonzie: This is really embarassing, huh? Some people got no class. They just interrupt a great meal. (to Joanie) Don't you ever do that, Shortcake.
Vivian: Fonzie, are you in there?
Fonzie: (shouting) Hey, will you shut up? We're eating! (edit) Howard: Hardware Village! It's three stories high, and it's got an escalator and a credit department and 600 different kinds of nails. You know how many kinds of nails I sell? Two: rusty and not rusty. (edit) Richie: This could really hurt Fonzie. He's a very sensitive person. I hope he doesn't throw me down the stairs. (edit) (Richie finds a reason to let Fonzie stay in the apartment above the garage.)
Richie: He's a very handy guy to have around. He can fix your car.

First "sit on it" phrase of the series. (edit)
