Mr. Monk and the Genius - S7-E2
Factual error: On the chessboard, both kings are in check, which is an impossible position in chess. (00:15:40)
Mr. Monk Gets Lotto Fever - S7-E3
Factual error: Since Stottlemeyer is accused of being involved in the lotto fraud he would not be allowed to take this case himself.
Mr. Monk Is Underwater - S7-E5
Factual error: Commander Whitaker tries to drown Monk and Natalie by trapping them in the ballast tank of the submarine. The ballast tanks on a submarine are inaccessible from the interior, and wouldn't have dramatic lighting in them either.
Mr. Monk Is Underwater - S7-E5
Factual error: Monk borrows Lt. Albright's sidearm to prove a point. All weapons on a submarine are locked in a small arms locker until needed, not carried around by officers. Further, medics are traditionally not issued firearms.
Mr. Monk Is Underwater - S7-E5
Factual error: The standard issue pistol for the US Navy is the 9mm Beretta 92F, not the Walther P38 as shown.
Mr. Monk Is Underwater - S7-E5
Factual error: Lt. Albright shows Monk and Natalie the "USS Seattle", a "Class 4 Submarine". US sub classes have names, not numbers, so she would be Los Angeles, Seawolf or Virginia class.
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: Attack submarines, like the one in the episode, do not have a medical officer on board. They have only what is called an Independent Duty Corpsman (IDC), who is a senior enlisted Hospital Corpsman and has had an additional year of special training to care for the medical needs of the crew, both routine and emergency.
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 Gets Hypnotized - S7-E8
Factual error: At the start of the episode, there is a double rainbow in the sky - both in normal order, while in fact the top rainbow should be mirrored.
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.
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.
