Adrian Monk: [to himself] Don't look down. Don't look down. [to Dr. Lancaster] How's the fishing, Doctor?
Dr. Lancaster: Monk. How did you get up here?
Manny: Santa Claus!
Adrian Monk: This is why you put Manny in that room, 'cause you knew you could spend all night up here and nobody would ever believe he really did see Santa Claus.
Dr. Lancaster: Nobody but you, Monk, and who's gonna believe you? You're clinically insane, remember?
Adrian Monk: We'll find the gun, Doctor, right where you dropped it. And that's all the proof I'll need. You couldn't stand it. The board of directors gave your job to Dr. Gould. You killed him. You stole some drugs to make it look like a patient did it. You needed a fall guy. LaFrankie fit the bill. You probably got LaFrankie all doped up, then lured him into the woods where the cops found him the next day. You only had one problem, the murder weapon. It was registered in your name. You had to get rid of the gun before the cops showed up. And you found the perfect place to hide it.
