Mr. Monk Gets Jury Duty - S4-E16
Continuity mistake: When the man with the letter from the Attorney General is telling Stottlemeyer not to 'screw it up', he is moving the letter in his hand. However, every time we see Stottlemeyer front on, there is a corner of the letter in the shot, and the letter remains stationary even while the other agent is moving it.
Mr. Monk Gets Stuck in Traffic - S3-E13
Continuity mistake: Throughout the highway driving sequence in the beginning, Natalie's rear view mirror disappears and reappears repeatedly.
Mr. Monk and the Genius - S7-E2
Visible crew/equipment: After Kloster catches Monk breaking into his house, the boom rigging's shadow can be seen moving on the wood-panelled wall in the background. (00:31:15)
Mr. Monk Is on the Run (2) - S6-E16
Audio problem: Toward the end of the episode, Mr. Monk runs out to stop the Governor's car before it crosses the banner and blows up. The first time that he yells out that "There is a bomb", you can see that Mr. Monk's mouth is not moving to say those words.
Mr. Monk Goes to Vegas - S3-E14
Continuity mistake: As Stottlemeyer steps off the stage, after singing, he is holding the microphone and pulls it down so that the top is pointed toward the floor but in shots following this, when he is talking to the woman, the microphone is back in an upright position.
Mr. Monk and the T.V. Star - S2-E12
Continuity mistake: The blood stains on Brad Terry's sweatshirt change positions after he runs back into the house. A few shots later, they're suddenly so faint they're barely visible at all anymore. Blood stains don't fade, at least not in just a few minutes.
Mr. Monk and the Other Detective - S4-E1
Continuity mistake: During Monk's therapy session, Dr. Kroger places his black folder on the arm of his chair. Every time the camera angle changes, the position of his right arm shifts from resting in his lap to lying on top of the folder.
Mr. Monk Goes to the Hospital - S5-E16
Revealing mistake: When Monk and the others are examining the crime scene, the "corpse" can be seen breathing (his abdomen is rising and falling) and blinking. There are various shots in this scene taken from behind the body looking into the room, and some of these are pulled back so that the body is visible while others are zoomed in so that it is not; this is not a mistake, but suggests that maybe the actor was told he would not be visible in these shots and so did not need to hold his breath.
Mr. Monk Joins a Cult - S6-E11
Continuity mistake: Just after Stottlemeyer and Natalie pull up to the curb to snatch Monk off the sidewalk, the boy and girl cult members instantly switch positions between takes. (00:27:00)
Visible crew/equipment: When the coroner's van pulls up in front of Cassie Drake's house, its shiny black side panel captures a clear reflection of the entire film crew. (00:27:00)
Mr. Monk and the Leper - S5-E10
Continuity mistake: When the body falls out of the balloon gondola, the weights that were securely tied to it have disappeared. The corpse also changes positions on the ground between shots, even though no one has touched it. (00:37:30)

Continuity mistake: When the victim's niece is crying and Monk is quizzing her about the house, the position of her hands changes instantly several times as the camera reverses angles. She holds her hands to her face as she cries, for instance, but in the very next shot, her hands are down at her sides. Next cut, they're up to her face again. (00:09:00)
Mr. Monk and the Three Julies - S6-E13
Visible crew/equipment: At the end, as Monk is summing up what happened, the shadow of the boom rigging intrudes into the shot on the right, against the backrest of the big green chair. (00:36:25)
Mr. Monk and the Sleeping Suspect - S2-E7
Plot hole: Technically, Brian Babbage's plan would never have worked due to the fact that all outbound mail goes to a main post office from the local post office and then placed through scanners to determine the contents, which would have inevitably exposed the bomb inside.
Mr. Monk Gets Jury Duty - S4-E16
Factual error: Since Monk has OCD it would be highly unlikely for him to be on a jury. Plus, Monk works for the police department and since he technically works in the criminal justice system, that would have made him exempt from jury duty.
Suggested correction: First, he would have to ask for exemption in writing prior to serving, with proof, regarding hardship for his OCD. While it's possible his doctor might say serving jury duty would result in physical harm due to his mental illness, it's unlikely to be given by Dr. Kroger. And Monk is not an active peace officer, so that wouldn't earn him an exception.
Mr. Monk Goes Back to School - S2-E1
Character mistake: Sharona invites Monk home for dinner. Monk is playing with his food, and Sharona guesses it is because the potatoes are mixed together with the carrots. Sharona asks Kyle to fetch two plates (So Monk can separate the potatoes and carrots.) As he tilts the dinner plate, Monk succeeds in scraping all the carrots onto one dish - save for one stray potato - all the while speaking. He completes his thought without removing the stray potato. In all other instances, Monk cannot allow such a transgression. He either corrects it before saying his piece, or after. But he cannot let it go.
Mr. Monk and the Miracle - S7-E9
Continuity mistake: At the dinner table, the liquid level in the Professor's water glass varies each time the camera angle changes. (00:21:00)
Mr. Monk Goes to the Office - S4-E4
Continuity mistake: When Monk and Natalie are talking to Kemp in his office, the desk ornament and the cup of pencils that Monk keeps organizing change positions between shots. In the shots from Monk's side of the desk, the ornament is closer to the door. In the shots from Kemp's side, the pencil cup is closer. (00:09:40 - 00:11:20)
Mr. Monk Is on the Run (2) - S6-E16
Continuity mistake: Stottlemeyer enters Natalie's house and closes the door behind him. A few shots later, even though it hasn't been touched again, the door is standing wide open. (00:06:20)
Mr. Monk Goes to the Office - S4-E4
Continuity mistake: When Monk is trying to join the two cops' conversation about football, in the shots from the side of the police car that they're standing near, the two cops are standing less than a foot apart. In the shots from the other side of the car, they're far apart enough for Monk, Natalie, and Captain Stottlemeyer to stand between them. (00:03:00 - 00:05:00)
