Harold Krenshaw: It's killing you, isn't it?
Adrian Monk: How did you do it, Harold? You've always been afraid of heights. You got vertigo when Dr. Kroger put in thicker carpet, remember?
Harold Krenshaw: I'm cured.
Adrian Monk: How?
Harold Krenshaw: It wasn't easy. I'll be honest with you. I don't think you can do it. You don't have it in you. It takes strength. I'm not talking about physical strength, although I've got plenty of that. I'm talking about... it.
Adrian Monk: It?
Harold Krenshaw: Yeah. The right stuff. Strength of character. I have it. Neil Armstrong has it. Rocky has it.
Adrian Monk: Rocky was just a movie, Harold.
Harold Krenshaw: Excuse me. I'm a little confused. I just fell off Telegraph Tower. How was your day? Here's what I do know. You don't have it, and you never, ever, ever, ever, ever, ever will!
