Natalie: I am not giving up, Mr. Monk. You're officially on notice. I am throwing you a party.
Adrian Monk: As a matter of fact, you are not.
Natalie: Oh, yes I am. We're gonna have balloons and cake and dancing.
Adrian Monk: Oh, for the love of God, why?
Natalie: Because, Mr. Monk, it's your birthday. And whether you like it or not, you have friends who love you and want to celebrate your life. We're happy you were born.
Adrian Monk: You're so cruel.
