Captain Stottlemeyer: Wallace Cassidy. He was on the jury when you were being sued six years ago.
Stewart Babcock: What are you talking about? Why would we care about somebody on a jury? That-
Adrian Monk: Maybe because you knew he was going to confess. Not for murder, for blackmail. Juror Number 12 was blackmailing you. He knew that you had murdered your first wife. After lan Agnew fell off your roof six years ago and sued you for negligence, the jury was brought here to visit the scene of the accident. One of them, Wallace Cassidy, wandered off. Most likely, he was looking for something to steal. Mr. Cassidy had a gambling problem. He was always in debt.
Sharona: I can't believe I went out with him. He's not even my type. I felt sorry for that stupid weasel.
Adrian Monk: Sharona?
Sharona: What!
Adrian Monk: We're working here. Mr. Cassidy never did find anything to steal. He found something a lot more valuable. It was the first Mrs. Babcock. He didn't leave without taking a picture and one of her fingers.
Captain Stottlemeyer: We have that picture, and we have the finger. It won't be hard to prove who it belongs to.
Adrian Monk: He sent you an anonymous note demanding money. You knew it was from one of the jurors, but you didn't know which one. At the time you didn't really care. Cassidy was small-time, and he wasn't asking for much. So you paid him and you thought that was the end of it. But it didn't end there. Cassidy kept coming back for more. So you decided to kill the blackmailer. But since you didn't know which of the 12 jurors it was, they all had to go, one at a time.
Sharona: Bastard! Not you.
Adrian Monk: Sharona, murderers, okay?

Adrian Monk: I couldn't prove a thing until I found this. Your shirtsleeve was torn off when you attacked Juror Number 11.
Stewart Babcock: Can you prove that's my shirt?
Adrian Monk: No, sir, I can't. But I know someone who can. As soon as I saw this, I had the strange feeling that the killer and I might have something in common. We both use the same dry cleaner.
Mrs. Ling: Mr. Monk, why you bring me here? I got to close my shop. I'm losing money. You're just my worst customer.
Lieutenant Disher: The longest car ride of my life.
Adrian Monk: I'm sorry, Mrs. Ling, but this is very important. Do you recognize this?
Mrs. Ling: Yeah. Yeah, I know this shirt. I clean this shirt. Silk. Beautiful shirt. Hanger, no starch. What you do to this shirt?
Adrian Monk: Mrs. Ling, there must be a thousand shirts like this in the world. How do you know you cleaned this particular one?
Mrs. Ling: You know how. The button, it fall off. I sewed it back on.
Adrian Monk: The thread is parallel, not crisscrossed. No one else sews a button on like this.
Mrs. Ling: I told you, Mr. Monk. That's my style! Always complaining about the button. Hey, Mr. Babcock! When I fixed this shirt for you, you don't complain, right, 'cause you're a good customer.
Captain Stottlemeyer: Mrs. Ling, are you certain that this shirt belongs to Mr. Babcock?
Mrs. Ling: Yeah, I'm sure. He's a good customer. You come back anytime, Mr. Babcock.
Lieutenant Disher: Ma'am, he just killed 11 people.
Captain Stottlemeyer: Twelve. Let's not forget about the first Mrs. Babcock, who I'll bet is buried under that new porch.
Mrs. Ling: Well, he's still a good customer. Not crazy like that Mr. Monk over there.

Sharona: What's this? I'm not paying for it.
Adrian Monk: It's your car!
Sharona: You didn't put money in the meter.
Adrian Monk: Okay, let's compromise. You pay the ticket, and I don't.
Sharona: What kind of compromise is that?
Adrian Monk: Well, that's the economical kind.

Adrian Monk: Thank you for seeing us.
Ian Agnew: Oh, I don't mind. I don't get many visitors. So, what can I do for you?
Adrian Monk: Mr. Agnew, we were wondering about your accident.
Ian Agnew: Please, sit down.
Sharona: Uh, lan, I used to be a nurse. Is there anything I can do?
Ian Agnew: No, thank you. It comes and goes. It's the pipe. I have a piece of pipe in my head.
Adrian Monk: Oh.
Ian Agnew: I don't get many visitors. Please, sit sit, sit, sit, sit, sit, sit, sit, sit, sit, sit.
Adrian Monk: Sir? Uh, about your accident?
Ian Agnew: Oh, the accident. I really don't remember much about it. I, uh We were building a cabana near the pool for the Babcocks, and, uh, I was working on the roof. And there was a a tile loose. And the next thing I knew, I woke up and I was a human smokestack. [all laugh] I'll get it! Hello? Hello? It's a wrong number. I get 'em all the time. How's that coffee? Bad dog. Anyway, I, uh I haven't worked since.

Ian Agnew: I'll get it! You know, I just changed my phone number and it doesn't seem to help. I don't get many visitors.
Sharona: Did you go to the trial?
Ian Agnew: I testified.
Sharona: Did you spend any time with the jury?
Ian Agnew: No, ma'am. I wish I had. Uh I wanted to thank them. They were very generous. I don't get many visitors. [sings] Daisy, Daisy, tell me your answer true... [shouts] Bad dog! You know what I think I miss the most? Not having this pipe in my head. I have to take this. Hello? Hello?
Sharona: [to Monk] I can't believe you're not the craziest man in the room.
