George: This is all too much. So what are you feeling? What's going on? Are you like a couple again now?
Jerry: Not exactly.
George: Not exactly. What does that mean?
Jerry: Well, we've tried to arrange a situation where we'll be able to do this once in a while and still be friends. (George laughs hysterically and stands out of his seat)
George: Where are you living? Are you here? Are you on this planet? It's impossible. It can't be done. (He sits back down) Thousands of years people have been trying to have their cake and eat it too. So all of a sudden the two of you are going to come along and do it. Where do you get the ego? No one can do it. It can't be done.
Jerry: I think we've worked out a system.
George: Oh, you know what you're like? You're like a pathetic gambler. You're one of those losers in Las Vegas who keeps thinking he's gonna come up with a way to win at blackjack.
Jerry: No, this is very advanced. We've designed at set of rules that we can maintain the friendship by advancing all of the relationship pitfalls.
George: Sure, all right. Tell me the rules.
Jerry: Okay. No calls the next day.
George: (To himself) So you're havin' the sex, next day you don't have to call. That's pretty good. (Back to Jerry) Go ahead.
Jerry: You ready for the second one?
George: I have to tell you, I'm pretty impressed with the first one.
