Adrian Monk: Oh, it's driving me crazy. How did he do it?
Natalie: Who?
Adrian Monk: Harold! Did you see him? He looked so not unhappy. And he wasn't acting, either. I could tell.
Captain Stottlemeyer: Excuse me, I'm sorry to interrupt you. But this guy says that, he never left the house. That he was here all night.
Adrian Monk: He's lying. What if it really works?
Natalie: What? What, hypnotism? Mr. Monk, just because Harold seems to be doing a little better doesn't mean it'll work for you. I mean, everybody's different. Especially you.
Captain Stottlemeyer: Excuse me again, sorry. How do we know he's lying?
Adrian Monk: The umbrella. Look, maybe it's real. It says "certified."
Natalie: What does that mean? Certified by who?
Adrian Monk: Whom.
Natalie: Whom. Mr. Monk, I just read this article on hypnotism. It's not even medical. It's a short cut.
Captain Stottlemeyer: Sorry, excuse me, one more thing. What about the umbrella?
Adrian Monk: Well, the green one on the end. It's monogrammed, it's obviously his. It's still wet from the rain.
Captain Stottlemeyer: Right, thank you.
