Quote from Lieutenant Disher in Mr. Monk and the Panic Room
Lieutenant Disher: Monk, can I run a theory by you? Adrian Monk: Sure. Lieutenant Disher: Suicide by monkey. Adrian Monk: Suicide by monkey? Lieutenant Disher: Yeah, what if Ian Blackburn trained the chimp to shoot him in the panic room? Adrian Monk: Why would he do that? Lieutenant Disher: So his wife could collect on the insurance. Thus, suicide by monkey. Sharona: Thus, theory by monkey. Adrian Monk: Randy, Ian Blackburn had a $100,000 life insurance policy. Chloe is worth, what, $20 million? It doesn't seem worth it. Lieutenant Disher: That's true. Sharona: You keep thinking, butch.
