Jerry: What's this all about?
Newman: Oh, we're making a trade. I'm giving him my motorcycle helmet, he's giving me his radar detector.
Jerry: I didn't know you had a motorcycle.
Newman: Well, my girlfriend had one.
Jerry: You have a girlfriend?
Newman: I had a girlfriend and she was pretty wild.
Jerry: I don't remember you with a girl.
Newman: Nevertheless...
Jerry: This is a pretty bad deal for Kramer. You know a radar detector is worth much more than that helmet. I think you're cheating him.
Newman: Don't say anything.
Jerry: All right.
[Kramer enters]
Jerry: Hey, you know you're getting gypped over here.
Kramer: Really? Ah.
Newman: We had a deal. Are you reneging out of the deal? Are you reneging? That's a renege.
Kramer: Oh, stop saying "reneging".
Newman: Well, you're reneging.
Kramer: Okay, okay. I'm not reneging.
