Quote from Adrian Monk in Happy Birthday, Mr. Monk
Natalie: How about a watch? Adrian Monk: I already have a watch. Natalie: Some people have two. Adrian Monk: Why would I want two? Look, if you have one wristwatch you always know what time it is. If you have two, you're never sure. Natalie: Well, Mr. Monk, I have to get you something, it's your birthday. Adrian Monk: Don't remind me. Natalie: And not just any birthday, you're 50 years old. That's a milestone. Adrian Monk: You know, you don't understand.
