Mr. Monk Goes to the Bank - S6-E12
Factual error: Banks never use combination locks. A four-digit lock, like the one used here, would take a patient thief about six hours to open by trying every possible combination, and banks really do take such unlikely scenarios into account. The wall panel in the bank would be secured by two padlocks, with no one person holding both keys.
Mr. Monk Goes to the Bank - S6-E12
Factual error: An intelligent, experienced police officer like Stottlemeyer would know perfectly well that shooting a lock will not open it – that's purely a Hollywood myth. Not only would shooting the lock probably jam it, but the ricochet in a closed room like a bank safe could easily kill someone.
Mr. Monk Is on the Run (1) - S6-E15
Continuity mistake: When Monk attempts to steal the truck at the gas station and grabs the sleeping driver's keys, he drives the truck in circles and then stops. When he stops, the truck is exactly parallel to the end of the concrete slab where the gas pumps are located. However, when the police arrive, the truck is now at a different angle with the back of the truck now being closer to the end of the concrete slab than the front. The gas station attendant would not have moved the truck himself as the police would have told him not to touch anything at the scene.
Mr. Monk and the Naked Man - S6-E3
Plot hole: SPOILER Arlene Boras swaps Peter Magneri's MRI scans for those of a healthy person in order to hide the fact that he has a potentially lethal aortic aneurysm. Clearly visible on the MRI scans she is holding are the dates and times of the examination - and the name of the patient. Swapping the records is pointless.
Mr. Monk and the Man Who Shot Santa - S6-E10
Continuity mistake: At the end, the glass of egg nog Julie and Natalie leave on the floor disappears after they stand up to talk to Monk. (00:40:40)
Mr. Monk Goes to the Bank - S6-E12
Continuity mistake: One of the large safety deposit box doors is standing wide open when Monk is curled up in the vault's corner. But when the camera angle changes, the door has closed itself. (00:30:45)
Mr. Monk Is on the Run (1) - S6-E15
Continuity mistake: Sheriff Rollins reports that his van had slowed for a yellow light when Monk escaped. But the van was driving down a forest road at the time. It was nowhere near any traffic lights. (00:24:10)
Mr. Monk and the Daredevil - S6-E7
Continuity mistake: At the end, the unconscious Cousin Joey changes positions on the roof. Though no one's touched him, he somehow shifts from lying curled on his side to flat on his back. (00:37:30 - 00:41:35)
Mr. Monk and the Daredevil - S6-E7
Continuity mistake: When Monk is trying to overcome his fears with Natalie and Julie's help, the blue pillow on the couch beside him alternates from lying flat to sitting upright, without being touched, throughout the scene. (00:17:00)
Mr. Monk and the Man Who Shot Santa - S6-E10
Plot hole: This episode's entire story line takes place in the six days before Christmas (Dec. 19-24). "Bad Santa" is shot in the right shoulder on the 19th, sustaining a wound serious enough to require wearing a sling for the next several days. Yet at the end, a mere few days later, he's recovered enough to have a knock-down-drag-out fistfight with Monk, wielding a knife and throwing powerhouse punches with his wounded arm as though no injury had ever occurred. (00:38:00)
Mr. Monk and the Birds and the Bees - S6-E5
Continuity mistake: The shape of the first ring Randy draws on the TV screen changes from an oval to a circle and then back to an oval between takes. (00:30:50)
Mr. Monk and the Birds and the Bees - S6-E5
Continuity mistake: In the mausoleum, the bald man asks Monk and Natalie what happened to the cremation urn name cards, and bends to pick one of them up from the floor. There are no cards on the table when he does this, but in the next shot, four cards have appeared on the table out of nowhere. A short time later, they've all disappeared again. (00:18:45 - 00:20:15)
Mr. Monk and the Three Julies - S6-E13
Continuity mistake: The broken side mirror that a distraught Stottlemeyer finds dangling from his damaged car wasn't there when Natalie pulled up to the first crime scene. And it disappears again when Natalie runs back to the car and races off to the second crime scene. (00:03:10 - 00:07:15)
Mr. Monk Is on the Run (1) - S6-E15
Continuity mistake: During Monk's fingerprinting session, the towelette packets on the counter change positions and quantity several times. (00:14:00)
Mr. Monk Is on the Run (1) - S6-E15
Continuity mistake: The items on the campsite table change positions radically just before Monk leaps up and knocks it over. Nothing is in the same place that it was just one shot previously. (00:22:30)
Mr. Monk Is on the Run (2) - S6-E16
Continuity mistake: When Monk is at the hotel, a teenage girl comes in to clean up the room. While they are conversing, the subject of mysteries comes up and she goes out and gets the newspaper and places it in front of Monk on the table. They then talk a little more about it and Monk gestures with his hands for her to take the newspaper away and she then picks up the newspaper off the table and exits the room with it. During this entire sequence, you can see that Monk does not ever touch the newspaper. Later on, at the car wash, Mr. Monk sees a newly-painted red SUV that used to be silver colored. When recalling that the teenage girl said that they were looking for a silver SUV, it now shows Monk pushing the newspaper across the table towards the teenage girl even though he never touched it in the original scene. (00:15:30)
Mr. Monk Is on the Run (2) - S6-E16
Continuity mistake: When Mr. Monk is attempting to turn off the key to the Governor's car, his right hand is clutching the top middle portion of the front windshield. However, one of the next camera shots shows the windowshield only with no hand at the top. Then a couple of camera shots later, Mr. Monk's right hand is now on the top of the dashboard. At the end of the sequence, his right hand is clutching the top middle portion of the front windshield again. (00:36:30)
Mr. Monk Is on the Run (1) - S6-E15
Plot hole: *Spoilers* Monk and Stottlemeyer cook up an ingenious plan to make Monk appear dead, but how the fugitive Monk acquires his regular clothes (in place of Mitch's uniform), the bullet-proof vest and the gun is not addressed. The police are watching Monk's apartment, Disher is watching Natalie and Julie, and Sheriff Rollins is watching Stottlemeyer, leaving us to wonder just how they managed all this right under their fellow cops' noses. (00:43:00)
Suggested correction: Stottlemeyer is a police captain. The sheriff can't watch his every move, and there are still plenty of cops who are loyal enough to Stottlemeyer for him to get one of them to deliver them to Monk or leave the items somewhere for him to retrieve.
Nice theory, but there's absolutely no hint of it in the episode. The lack of any explanation creates a bit of a plot hole because it leaves us wondering.
Mr. Monk and the Rapper - S6-E2
Factual error: Extra Large was killed Sunday morning of Daylight Saving's Day. But the paper they show Monk is dated Friday, May 4, 2007. But Daylight Saving was March 11, 2007.
Mr. Monk and the Three Julies - S6-E13
Factual error: Monk deflects the policeman's rifle shot and the bullet hits Stottlemeyer's car. But the gun fires just as Monk pushes it aside, and the car is behind them. There's nothing that could deflect the bullet back toward them, so at that angle, there's no way the shot could have struck the car. (00:35:50)
