Quote from Newman in The Diplomat's Club
Newman: Okay, here it is. Kramer: Good. (To Earl) Here's my collateral. Earl: So it's a mailbag. So what? Newman: So what? Do you know whose mailbag that is? Earl: "David Berkowitz." Newman: Son of Sam. The worst mass murderer the post office ever produced. Earl: Where did you get this? Newman: I took over his route. And boy, were there a lot of dogs on that route. Earl: Any of them talking to you? Newman: Just to tell me to keep off the snacks! [all laugh] Earl: [to Kramer] Your buddy's a hell of a guy. Kramer: Yeah, don't I know it.
