Natalie: Please, Mr. Monk. You are so brilliant. It wouldn't take you more than a couple of hours. Look, I promised him. It can count as my birthday gift.
Adrian Monk: I didn't plan on buying you a birthday gift.
Natalie: All right. I'm cashing in my chips.
Adrian Monk: What chips?
Natalie: My karma chips. I've been collecting karma chips every week, every day, every time I do something stupid for you.
Adrian Monk: It's your job. You're paid. Semi-regularly.
Natalie: Yeah, I'm not talking about my job. I'm talking about all the other stuff. I've been babysitting you for five years. I've collected, like, a thousand chips. And I'm cashing them all in. I'm all in. You have to help me find the bike.
