Quote from Adrian Monk in Mr. Monk and the Three Pies
Ambrose Monk: I save all my mail. When Dad comes back he'll want to see his mail. Adrian Monk: Ambrose. Ambrose Monk: It'll be all ready for him. Adrian Monk: He's not coming back. Ambrose Monk: You don't know. Adrian Monk: Yes, I do. Ambrose Monk: You don't know everything! Mr. Great Detective! Why aren't you out there looking for him? Adrian Monk: 'Cause I'm afraid I might find him.
