Mr. Monk Goes to Jail - S2-E16
Continuity mistake: When Monk and Sharona talk to Sylvia in the prison library the second time, the books on her desk change in various shots. At first, you see 3 piles of books, all with blue books on top. In the next shot the blue book closest to her is gone. In the next shot, she's straightening a red book next to her, but it goes back to being crooked.
Mr. Monk and the Very, Very Old Man - S2-E5
Continuity mistake: When the Captain is eating his sandwich while talking to Monk, the position of the sandwich and amount eaten keeps changing. He'll have it in his hand, but in the next shot it's on the plate. And you see him take a 2nd bite, but later only 1 bite has been taken.
Mr. Monk Takes a Vacation - S1-E10
Continuity mistake: When Monk is talking to Benjy, he buttons up the top two buttons on his shirt, but in the next shot of him they're undone, and he's re-buttoning them.
Mr. Monk and the Billionaire Mugger - S1-E7
Continuity mistake: When Stottlemeyer pulls his gun on Mr. Modine, the safety is off and the gun is cocked, but in the next shot it's not cocked and the safety is on. Then we see the safety off, but not cocked.
Mr. Monk and the 12th Man - S2-E9
Visible crew/equipment: When Monk is talking to Dr. Kroger about Sharona's new boyfriend Kenny, you can see the cameraman's reflection in the window behind them. (00:09:26)
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 and the Captain's Marriage - S4-E12
Continuity mistake: While at the crime scene in the junkyard, Monk is trying to explain things, but is unable to concentrate because one of the stacked junked cars still has a headlight in it. Frustrated, the Captain shoots the light out so Monk can continue, but as the screen pulls back the headlight is still unbroken in the car.
Mr. Monk and the Candidate (1) - S1-E1
Continuity mistake: When Mrs. St. Claire refers Mr. Monk as "Rain man", her glass is about an inch and a half full. Next time we see her the level of liquid has dropped. (00:16:45)
Continuity mistake: In the flashbacks of Sharona's uncle's fall, he's lying perpendicular to the steps, but in the photos of the incident we saw earlier, he was lying in line with them. In fact in the last flashback showing the murder his position changes again, turning from a 90 degree angle to be more like 45.
Mr. Monk and the Class Reunion - S5-E6
Continuity mistake: During the touch football game, when Natalie first throws the ball to Monk, he catches it and a guy in a blue T-shirt and jeans is running up behind him. Angle switches as Monk twists out of the way, and it's a different guy wearing black shorts instead. A few cuts later and Monk runs past the same guy in black shorts again.
Mr. Monk Gets Married - S2-E15
Continuity mistake: In the room with the memoirs, Monk turns around and reaches towards a few slightly misaligned books to take one and read it. In the closeup, it's a neatly stacked shelf.
Mr. Monk and the Missing Granny - S2-E13
Continuity mistake: Monk identifies the kidnappers' house by the pizza box outside by the bin. In the wide shot it's upside down on its corner, with "zza" just visible behind a black bag. In the closeup it's turned around, so we can see more letters, and it's moved.
Mr. Monk and the Paperboy - S2-E10
Continuity mistake: Stottlemeyer says "does that make any sense to you?" as Monk is straightening the pots on the mantelpiece - all the lid handles are horizontal. The camera cuts away for a second, cuts back, and the lid on the far right has suddenly rotated 90°, whereupon Monk straightens it to be horizontal like the others.
Mr. Monk and the Girl Who Cried Wolf - S3-E6
Continuity mistake: When Meredith's husband has his heart attack, his head falls into the soup bowl. However, in one shot the bowl (with his head in it) is tilted; after a cut, it is suddenly flat on the plate.
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.
