Ralph: I knew a girl who lived in New York for one month, and, when she came back, she knew everything. Arlene's been there three years. You know what that means?
Fonzie: She's a slow learner?
Fonzie: I went out with a girl like that once. Broke up with her in two and a half minutes.
Richie: How did you do it?
Fonzie: Well, I wrote a note and threw it through her window. Of course, it was wrapped in a brick.
Richie: She said she'd do something desperate.
Ralph: How desperate can you get in a ladies' room?
Richie: Do you know what's in a ladies' room?
Ralph: No, do you?
