Mr. Monk and the Really, Really Dead Guy - S5-E15
Continuity mistake: In the scene where Monk mistakes the plasma TV for a blackboard, he writes the words "BODY MOVED" on the screen. Initially, he writes the "B" with an extra long vertical stroke; the next time we see the text, the vertical stroke is of a normal length. The text reads "BODY MOVED" when Monk stops writing, but when the FBI agent walks over to the screen to try to wipe it off, it has changed to "BODY M".
Mr. Monk Goes to Jail - S2-E16
Factual error: Death row prisoners cannot donate organs. No doctor participates in an execution and after the lethal injection the medical examiner must wait at least fifteen minutes to test for cardiac activity before pronouncing the prisoner dead. This is enough time for hypoxia to render the heart, lungs and kidneys useless for transplant. Apart from this, organs intended for transplant must be removed within minutes of the death of the donor. Prisoners are not executed in operating theatres.
Adrian Monk: Here's what happened.
Mr. Monk Joins a Cult - S6-E11
Trivia: The cult leader, Ralph Roberts, is played by Howie Mandel of Deal Or No Deal, who suffers from OCD in real life.
Question: If Monk is afraid of germs, then why does he keep touching things that could possibly have germs on them like parking meters or books?
Answer: That's the thing about Obsessive Compulsive Disorder. It's not something rational. He just has to touch things like that. It's not something he can rationally think through. However, since part of his disorder includes an obsession with cleanliness, he also has an assistant walk around handing him wipes periodically. It's like when he gets a cold and uses both a humidifier (because that's what you use when you're congested) and a dehumidifier (to counteract the effects of the humidifier). He may spout rationalizations after he does something, but his compulsions exist outside of any rational thought whatever.
Answer: Notice also that in the opening credits scene when he is touching parking meters her also wipes his hand on his clothes each time he does it.
