Adrian Monk: Okay. He slipped through the bars and out the bathroom window.
Captain Stottlemeyer: How?
Adrian Monk: He wiggled through. He's a nudist. They're all double-jointed.
Lieutenant Disher: They are?
Adrian Monk: Randy. Don't be so naive. They're not like us. All right, look, I-I have a theory. I- I think- I think they secrete a fluid. It's like an oil. It's odorless, but I can smell it. It makes them all slippery. They can wiggle through anything. They're like slugs.
Captain Stottlemeyer: Monk, nobody wiggled through anything. There was a guard on duty all night.
Adrian Monk: Then he's in on it too. He's one of them.
Captain Stottlemeyer: Well, what about the 20 cops that are outside?
Adrian Monk: They're all in on it! Don't you see? It's a cabal.
Lieutenant Disher: What?
Adrian Monk: A cabal. It's a secret society. Sometimes they're naked. Sometimes they go around dressed to confuse us.
Natalie: Well, they're certainly doing that.
Adrian Monk: Have you read their literature? I have. They want to convert us all. And they won't stop until we're all like them, on beaches, in parks, hanging out everything hanging out. Hanging and hanging. Captain, there's only one way to deal with them. We gotta ship them back.
Captain Stottlemeyer: Ship them back where, Monk?
Adrian Monk: Exactly.
