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.
Mr. Monk Joins a Cult - S6-E11
Continuity mistake: Ralph has his hand on Monk's shoulder during the applause, but after a cut, his hands are both suddenly stretched into the air. (00:21:50)
Mr. Monk Takes Manhattan - S3-E1
Continuity mistake: The angle of one of the victims' heads visibly changes from shot to shot while Monk is investigating the scene. (00:05:30 - 00:06:25)
Continuity mistake: When Linda is showing the apartment to the Captain, she has her phone in her left hand and crosses her arms. Her arms stay crossed, but then in a later shot, with her arms still crossed, the phone is in her right hand.
Continuity mistake: When Jay pulls up to the marina, he parks at an angle and quickly jumps out and then we see him take off in his boat. When the Captain arrives, Jay's car is no longer at an angle and is parked properly.
Continuity mistake: When Monk and Al are sitting to drink wine, Al grabs his bottle with one hand to pour the wine and the other hand is hanging down to his side. In the next shot, as he's pouring the wine, he's holding the glass with the other hand. In the next shot, his hand is by his side again.
Mr. Monk Gets Stuck in Traffic - S3-E13
Continuity mistake: When Monk is talking to Daniel on the radio, in the shots from inside the truck, Krystal is standing next to the open door, to Monk's left when he turns to face her. In the shots from outside the truck, Krystal is now away from the door and to Monk's right.
Mr. Monk Gets Stuck in Traffic - S3-E13
Revealing mistake: When we see a shot of Steve in his car while in the dump truck, it's shot in a studio and the shot is reused each time we see Steve in the car. The shadow is completely different and at one point, when they show Steve in the car with the car and truck bouncing around, you can tell the image is just shaken, rather than the dump truck actually bouncing. There are loose chains hanging off the inside walls that don't move or sway at all.
Mr. Monk Gets Married - S2-E15
Continuity mistake: In Dalton's antique store, in the close of the forged map, the "sold" tag is covering part of the state names (mainly the West in West Virginia) and part of the picture. In the wide shot, the tag is now in the corner and not covering anything.
Mr. Monk and the Big Reward - S4-E13
Continuity mistake: During grocery checkout, the vegetable oil keeps shifting around between shots, from next to the clerk to behind the cereal. (00:06:00 - 00:07:00)
Mr. Monk Makes A Friend - S5-E11
Revealing mistake: During the fight scene in the restaurant kitchen you can see that the woman is a stuntman, you can even see the horrible wig pop up off the stuntman's head a few times.
Mr. Monk Goes Back to School - S2-E1
Other mistake: Derek tells Beth to meet in their "usual spot" the next day at 8am. The next scene has Derek sitting at his desk and it looks like the kids are already in deep with their SAT tests. Beth falls at 8:25am (as per the clock in the testing room.) There is no way that Derek could have killed Beth, put her on the minute hand (later in episode on the Monk recap, it has 8:15am. If Derek was proctoring a SAT test, I don't know of any that start around 8:20 and immediately in depth.
Mr. Monk Goes Back to School - S2-E1
Factual error: In the cold opening, Derek said that his wife is very smart and got a 1680 on the SAT. This episode takes place in 2003, the writing portion that was added to make the max (2400, not 1600) was in 2005.
Character mistake: It seems throughout the whole series at crime scenes Monk, Randy, and Stottlemeyer handle evidence bare handed. Surely, they should be wearing gloves so as not to contaminate the evidence.
Mr. Monk Goes to Jail - S2-E16
Factual error: The murdered man is killed by poison while having his last meal just before they execute him that night. Death row inmates have their last meal one to two days before they're executed.
Mr. Monk and the Big Game - S5-E3
Factual error: All the players have their first names on the back of their jerseys. They should have their last names on the jerseys for better identification considering some of them would probably have the same first name.
Suggested correction: This isn't a mistake just because a school does it a different way than what you expect. Not to mention that some people also have the same last name, so using the last name would create the same "problem." All they would have to do is add a last name initial.
Mr. Monk and the Birds and the Bees - S6-E5
Other mistake: Monk wasn't afraid of heights, as he climbed on a chair to unscrew a vent.
Continuity mistake: When Monk takes the dog to the park, they're standing on the curb by the grass when he goes to take the leash off. After he says "get ready", the shot changes and they're not by the curb anymore. They're back on in the next shot.
Mr. Monk and the Sleeping Suspect - S2-E7
Character mistake: Brian Babbage is such a perfectionist and plans out such an elaborated plan for his crimes that it is very unlikely that he would simply leave the ketchup bottles sticking to the ceiling for the police to be found after he had timed the perfect glue for his plan. Plus, he even had staffers who already knew about the bottles and it would have taken him not more than a single order for the bottles to be removed. (00:23:50)
