Natalie: Oh, my God. He's coming. What do we do? We should kiss. No! I didn't say that. I wasn't thinking. I never said that.
Patrick Kloster: Good morning. I thought you might be thirsty. Well, this is for you, Natalie. It's lemonade. And, Mr. Monk, I believe this is your brand. Oh, my books. I could autograph one for you.
Adrian Monk: No, thank you. No.
Patrick Kloster: Very well. I'll leave you two alone. Enjoy your little stakeout.
Natalie: Well, you have to admit, he's pretty good. What? He was right. I was thirsty.
Natalie: What?
Adrian Monk: How do you feel?
Natalie: Uh, I feel fine. What?
Adrian Monk: It just occurred to me. If there's poison in that lemonade, we could go to the D.A., and we'd have all the evidence we need.
Natalie: [spits out] It just occurred to you, and you didn't say anything? My God, Mr. Monk, I have never seen you like this. [pours the lemonade away]
