Mr. Monk Bumps His Head - S4-E11
Other mistake: The diner Monk enters to eat something after the truck driver gave him five bucks is the same diner that Christie and Sharona are waiting in to meet Monk after work in the episode Monk and the employee of the month. But while this episode is said to be in Wymington, the earlier one is set in San Francisco.
Suggested correction: This is trivia at best. While the set may be reused, it's not meant to be the same diner. It might be a chain restaurant so they look similar, but the seats inside are different.
Mr. Monk and the Psychic - S1-E3
Plot hole: When Monk is looking for the pebble, he immediately makes an announcement through the shop's speaker system and then directly asks the guy wiping the floor where the rest of the garbage is. Given the size of the trash can it is not realistic that the guy wiping could have filled the trashcan, emptied it and have it filled half again in the 2 to 10 minutes that might have passed since the pebble got lost.
Mr. Monk Gets Lotto Fever - S7-E3
Continuity mistake: Right after the taxi driver drives off and the couple approaches Monk and Natalie there is a man passing by right behind the couple, but when camera angle changes within a split second that man is gone.

Revealing mistake: When Natalie visits Dale in prison you can tell that Dale is wearing a "fat suit". The suit on his arm is folding up on itself like a glove.
Other mistake: Mr. Monk is solving his 100th case, but in Season one Episode 3 Julie gives him 100 trophies, saying they rounded down from 104 to make an even number.
Mr. Monk and the Other Woman - S1-E8
Plot hole: Monk's led to the killer because he figures out that he "added a file" to the lawyer's filing cabinet, judging by the left/middle/right tabs being off. But this makes no sense on two levels - firstly why would he need to add a file? He was just replacing the real will with a forgery. He just took the old one out and added the new one, he didn't need to mess with the filing system at all. Secondly, he picks that one out because the tabs are offset, but what if the lawyer had just taken on a new client or added other paperwork? Then the tabs would be off too, but that never seems to be considered.
Mr. Monk Goes to the Carnival - S1-E5
Continuity mistake: When Kitty runs up to Gitomer, she is not wearing gloves. Later, when Monk gives his summation, careful viewing will show Kitty wearing a glove that's used to hold the knife.
Mr. Monk Gets Jury Duty - S4-E16
Factual error: When Natalie hears the jury's muffled screams inside the locked room she uses the fire extinguisher to tear off the door knob. But a locked door without a knob is actually only harder to open, because like that you cannot turn the mechanism even if it was unlocked.
Mr. Monk and the Really, Really Dead Guy - S5-E15
Factual error: Monk typing the address into his laptop would not affect the trace the agents are doing, it definitely wouldn't pop up on the agent's screen as the result of the trace.
Mr. Monk and the Man Who Shot Santa - S6-E10
Other mistake: When the star of Bethlehem is stolen, the shots are reused from episode 4-13, with a flail used to breach the glass case, which isn't present in this episode.
Mr. Monk and the Other Woman - S1-E8
Audio problem: When Monk finally turns around at the funeral to tell the old man behind him to be quiet, you can still hear the man coughing. But the man's face is still, and his mouth is not open, and he isn't making the sound.
Mr. Monk and the Buried Treasure - S6-E6
Continuity mistake: In the captain's office, Randy is holding his cup with both hands and he states that he has a Motorola phone in his pocket. He begins to turn to his left to expose his suit pocket jacket. In the very next shot, which is a wide angle of everyone, he is beginning his turn again so Natalie can retrieve the cell phone.
Mr. Monk and the Buried Treasure - S6-E6
Continuity mistake: At the end of the episode, when Dr. Kramer and Monk are talking, Dr. Kramer is hunched over listening to Monk. In the very next camera shot, with the camera pointing at Dr. Kramer, he is sitting straight up and just finishes crossing his arms. A couple of seconds later, it switches back to Monk and you can see Dr. Kramer hunched over again and arms uncrossed.
Mr. Monk and the Very, Very Old Man - S2-E5
Continuity mistake: When Stottlemeyer moves the snake, the pinecone falls on the ground. The next scene, where Monk is on the table and talks to Stottlemeyer, the pinecone is back on the shelf. (00:25:26 - 00:26:36)
Mr. Monk Takes Manhattan - S3-E1
Deliberate mistake: After Monk and Sharona speak to Gratnik in Dumbo, they take the subway back to Manhattan. While Monk is sobbing, in the first exterior shot the "A" train slows into the 42 St station in Manhattan; note the "A" at the left with the driver on the right, as well as the "42" station sign not reflected backwards, all revealing a flipped shot. Then it's the "C" train when it stops, with Monk and Sharona back in Brooklyn, even further now at the "Hoyt-Schermerhorn Street" platform (used for TV shows and films), in lower Downtown Brooklyn. (00:21:55)
