Quote from Judy Geller in The One with Monica and Chandler's Wedding (Part 1)
Ross: Mom? Dad? What are you guys doing here? Jack Geller: Well, you guys talk about this place so much. We thought we'd see what the fuss is all about. Judy Geller: I certainly see why the girls like coming here. Ross: Why? Judy Geller: The sexy blond behind the counter. Ross: Gunther? Jack Geller: Your mother just added him to her list. Ross: What? Your list? Judy Geller: Yes, the list of people we're allowed to sleep- Ross: No, no. I know what the list is.
