Mr. Monk Gets Hypnotized - S7-E8
Revealing mistake: There is an obvious stunt double when Monk is fighting with Sally Larkin for the piece of chewing gum: he is younger, more tanned, and possibly wearing a wig in order to emulate Tony Shalhoub's hair. (00:35:55 - 00:39:05)
Plot hole: How come Monk and Natalie didn't think it suspicious that Cassie Drake was killed in her house within less than twelve hours after they had found out she was responsible for killing her patient? Since Jake and Ramone were the only two people they had disclosed their findings to (apart from Stottlemeyer and Disher), they should have focused in on Jake much sooner. (00:24:00 - 00:27:00)
Mr. Monk and the Genius - S7-E2
Continuity mistake: As soon as Monk finishes his summation to Patrick Kloster during the funeral parlor scene, he tells Natalie to call Stottlemeyer, and she walks away to get some privacy. Natalie is still in the background, a few feet away, when the two elderly mourners come in and Monk mistakes the woman in the coffin for the murder victim. Natalie is still visible behind the mourners for the first few shots, but then disappears, and suddenly is standing right beside Monk. (00:19:00 - 00:21:00)
Continuity mistake: The first victim's body and the floor around her are covered with pieces of glass, but the hole in the pane of glass is only about the size of a fist, not nearly big enough to leave that much glass on the ground.
Continuity mistake: Monk eats a sandwich with a slice of one of the square tomatoes on it, however, in "Mr. Monk Goes to the Asylum," tomatoes are one of his allergies.
Mr. Monk's Other Brother - S7-E10
Factual error: In the scene where Monk is making pancakes in his kitchen, he is using a stainless steel spatula on a teflon-coated griddle pan. Mr. Monk has OCD and would never risk scratching his pan with a metal utensil.
Mr. Monk Is Underwater - S7-E5
Factual error: The clip of a submarine surfacing near the end of the episode does not show a normal surfacing; it shows a submarine that has blown its ballast tanks using high-pressure air, which is an emergency procedure that is practised only occasionally. The reason it is not done routinely is because the submarine comes up like a cork with very little control.
Mr. Monk Is Underwater - S7-E5
Factual error: One of the most common firearm tropes on TV and in movies is that using a suppressor (aka, "silencer") reduces a gunshot to a whisper. In reality, a suppressor (either commercial or homemade) only reduces the sound of a gunshot from as loud as a jet taking off to "merely" as loud as a jackhammer.
Mr. Monk Is Underwater - S7-E5
Factual error: Smoking is not permitted on a nuclear submarine; in fact, the atmosphere is so tightly controlled that not even shoe polish is allowed. Also, alcoholic beverages are prohibited.
Mr. Monk Is Underwater - S7-E5
Factual error: Officers do not wear their summer whites on board a submarine. Although navy working uniforms have changed since this episode of Monk was made, at the time, all personnel on submarines, both officer and enlisted, wore the same type of dark blue coveralls when on board. Rank was distinguished by pin-on devices on the collars.
Mr. Monk Is Underwater - S7-E5
Factual error: In the episode, the submarine dives almost as soon as it is underway. Submarines do not dive until the water is at least 600 feet deep.
Mr. Monk Is Underwater - S7-E5
Factual error: Nuclear submarines do not get underway on the spur of the moment. It takes hours to make preparations for getting underway. Also, the submarine would not get underway until a new executive officer had been assigned.
Mr. Monk Is Underwater - S7-E5
Factual error: The captain's stateroom shown in the episode is palatial compared to reality.
Mr. Monk Is Underwater - S7-E5
Factual error: One does not simply walk onto a nuclear submarine. Security is very tight, access is strictly controlled, and visitors are escorted at all times and are restricted from seeing certain areas. In this episode, whenever the exterior of the submarine is shown, there is no sign of an Officer of the Deck or a Petty Officer of the Watch, much less any security personnel nearby.
Mr. Monk Makes the Playoffs - S7-E13
Other mistake: At the end when Bob Costas is signing off, the mic is in his right hand with the window on his right). When it switches to Natalie watching the upside down TV, the image on the screen is a flipped image (so that the mic is in his left hand and window is on his left). The broadcast wouldn't be a flipped (or mirrored) image than what we see, otherwise, everything the viewer is watching would be backwards (like the writing and numbers).
Mr. Monk and the Genius - S7-E2
Character mistake: At the beginning when Monk is writing Natalie's check, we see a shot of it, but the I in "nine" isn't dotted. As meticulous as he is, Monk would never leave an I undotted (we've even seen him dot someone else's i) especially since it would bother him.
Mr. Monk Makes the Playoffs - S7-E13
Revealing mistake: When Monk steps in front of the limo to stop it from leaving, on the bottom right of the screen there's a black line that doglegs to the right (seen over Monk's coat sleeve). It's like the camera was cracked or something was stuck to it. When the camera angle changes it's gone, but is there where the camera is back on Monk.
Mr. Monk and the Miracle - S7-E9
Continuity mistake: When Natalie enters Monk kitchen with a bag of groceries, from one angle the bag is on top of the cutting board. In the side angle she is removing items from the bag on the counter. (00:17:57)
Mr. Monk Falls In Love - S7-E6
Continuity mistake: The woman sitting and waiting, in the red with a green scarf, is sitting without anyone to the right of her. After a cut, suddenly a man appears sitting next to her on the right. (00:06:45)
Continuity mistake: The Captain hits the murderer at the end with his left hand. In the next shot of the Captain he is shaking his right hand as though that is the hand he used to hit the murderer.
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.
