Gwen: Kramer, hi.
Kramer: Oh, hello.
Gwen: It's Gwen. We met at the coffee shop.
Kramer: Uh-huh?
Gwen: I'm dating your friend, Jerry.
Kramer: Ah, I don't know who you really are, but I've seen Jerry's girlfriend, and she's not you. You're much better looking and like, a foot taller.
Gwen: That's why we're always hiding in that coffee shop! He's afraid of getting caught.
Kramer: Oh, he's a tomcat.
