Mr. Monk and the Paperboy - S2-E10
Continuity mistake: When Monk says "I can bench 200", you can tell he has his arms by his sides, but in the next shot, his hands are held up at the level of his waist. (00:12:15)
Mr. Monk Is At Your Service - S5-E12
Continuity mistake: Monk finds the magazine from which the butler cut out words for his blackmail note, and matches a scrap with the word "Police" on it to the article it was cut from - only the left and bottom edges of the scrap don't conform at all to the hole cut in the page. They haven't been trimmed more. In fact, the whole piece is much too large to fit into the space. (00:36:30)
Continuity mistake: When Natalie props the get-well card up on Monk's bureau, it's partially open. The moment the shot cuts to a different angle, it's completely closed. (00:10:15)
Mr. Monk and the Big Game - S5-E3
Continuity mistake: During a 30-second timeout, the scoreboard in the background is counting down the time. As the scoreboard hits 12 seconds, the shot changes to Mr. Monk and the team huddle. The scoreboard appears again in the following shot, for the remainder of the timeout. When the scoreboard reappears, the clock has more than 12 seconds on it.
Mr. Monk and the Daredevil - S6-E7
Continuity mistake: Monk drops the harmonica onto the coffee table, and it lands in a horizontal position. Monk doesn't touch it again, but it moves to a diagonal orientation and then back to a horizontal one between takes. (00:18:15)
Mr. Monk Is On The Air - S5-E13
Continuity mistake: As the murderer is arrested at the end, the collar of his jacket changes from turned up in back to turned down, etc., several times between takes. (00:39:30)
Factual error: As Monk is removing the crumbs off the keyboard, he flicks one crumb away from the backspace key. It gets flicked up and lands near the 0 button on the numeric keypad. Yet when this happens, the screen then says "Do you want to delete files?" as if he hit the delete button.
Mr. Monk and the Blackout - S3-E3
Visible crew/equipment: During the police investigation at the power station, the shiny blue construction helmets show us the stage lights, reflectors, camera and film crew several times. (00:09:00)

Mr. Monk and the Captain's Wife - S2-E14
Continuity mistake: In the pre-credits sequence, Karen attaches a clip to the right side of Leland's shirt, but a few seconds later, there is none on his right side. They are all on his left side. They also disappear and reappear.
Mr. Monk and the Captain's Wife - S2-E14
Visible crew/equipment: When Karen and Leland are arguing, a crew member is visible in the van's side window in the left of one shot.
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.

Continuity mistake: In the flashback scene of the kids in the school hallway, the autographed photo of Patty Duke disappears and reappears twice on the inside of Little Monk's locker door as the camera angles change.
Mr. Monk Is Up All Night - S6-E9
Factual error: [SPOILER ALERT] At the end of the episode, it is revealed that the mysterious cab driver had corneal transplants to repair damage to her vision from Retinitis Pigmentosa. RP is a defect of the retina, in the back of the eye, which accumulates pigment, losing its photoreceptivity, resulting in vision loss. A corneal transplant will not restore vision to someone with RP.
Mr. Monk and the Astronaut - S4-E14
Plot hole: The murderer mails a garage door opener with the button taped down to his victim and kills her by remote. But A) With the switch continuously in the "on" position, the battery would die long before the package arrived, and B) Door openers use special frequency tones that are set much like a safe combination. The likelihood of one control opening 3 different doors in the same area, as it does here, is virtually nil. (00:33:30)
Mr. Monk Is on the Run (2) - S6-E16
Continuity mistake: In the motel room, the newspaper clippings and the scrapbook Monk has been working on change their arrangement on the table between shots as the owner's daughter and her dog are leaving. (00:10:30)
Mr. Monk and the Three Julies - S6-E13
Character mistake: Julie has just passed her driver's test. At the end, she drives up with two teenage friends in the car and offers the stranded Captain Stottlemeyer a ride. Instead of simply accepting, by-the-book cop Stottlemeyer would be lecturing her. California law prohibits new teenage drivers from having other teens in the car. (00:40:15)
Mr. Monk and His Biggest Fan - S6-E1
Continuity mistake: In the lumber yard, Randy shows a rare streak of genius by knocking out the bad guy with a 2x4 shoved through a stack of boards. When the 2x4 strikes Ringel, it stops its slide protruding about six inches from the stack. When the camera angle changes for the very next shot, the 2x4 is suddenly sticking out more than a foot. (00:39:30)
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.
