Natalie: What did she say?
Adrian Monk: She's not the guy.
Captain Stottlemeyer: Well, you keep saying that. But how do you know?
Lieutenant Disher: Captain, check this out. It's from the collection box. A Zemenian ten dollar bill. That's the piece of paper we found in the cab.
Captain Stottlemeyer: Nobody bats a thousand, Monk. That's a perfect match.
Adrian Monk: What? perfect? You don't know that it's perfect. Don't you think I'd be the one to know if it's perfect? Well, it's not. Probably.
Captain Stottlemeyer: Okay, we'll go to the lab and make sure it's perfect.
