Adrian Monk: All right. I am the inventor. I am Kurt Pressman. [to T.K.] I'm sorry, I don't have a part for you. Okay, I walk across the room carrying two glasses of soda. I step up.
Lieutenant Disher: That's right. He wasn't sure which one was diet, so he took a sip. Then Meckler's wife takes a sip. She took a sip. She gave the glass to Meckler. He drank from it. Five minutes later he was dead.
Adrian Monk: So how was he poisoned? That's the question.
Natalie: Well, it had to be in the drink.
Lieutenant Disher: No, that's- That's impossible, Dr. Z said the poison hits you like this. And he was sipping it for at least five minutes. Besides, his wife and Pressman both drank from the same glass, they didn't even get sick.
Captain Stottlemeyer: So it wasn't in the drink. Was he eating something?
Lieutenant Disher: No.
Natalie: Wait a minute. He was chewing on his pen, like a nervous habit.
Captain Stottlemeyer: Nope, it wasn't the pen. That was the first thing we tested. It was clean.
