Sgt. Danny Weaver: What's that?
Adrian Monk: Looks like a coupon. 30 cents off Hardy Chow dog food. He didn't follow the line. You see, the dotted line there.
Det. Sgt. Louis Doyle: Well, not everybody's you. Thank God.
Adrian Monk: Do you have a dollar? [Doyle hands him a dollar] It's the same size. It was a payoff. That's what he was doing here. Somebody was paying DiMarco off, or that's what DiMarco thought. He cut up newspaper into dollar-sized pieces; make it look like cash.
Sgt. Danny Weaver: Why?
Adrian Monk: To distract him. To put him off guard. And then they shot him.
Sgt. Danny Weaver: Or he had a dog, and he just wanted to save 30¢.
Adrian Monk: It was a payoff.
Sgt. Danny Weaver: Monk, come on. Look, the captain's gonna be here in a few minutes. I want to get this straight. Are you saying this kid is dirty?
Adrian Monk: It would explain everything. Why his safety is still on and his gun is holstered.
Sgt. Danny Weaver: I'm not saying you're wrong. You might be right. But here's what I am saying. Until you're sure, until you're 110%, hmm? You're to shut your face. Do you understand that? You're on this side of the blue line now, Detective Monk. That kid is family. So I'm gonna ask you one more time. Are you 110%?
Adrian Monk: No.
Sgt. Danny Weaver: Then button it.
