Mr. Monk Takes Manhattan - S3-E1
Continuity mistake: When Monk is lost in the street crowd after getting pushed into the subway car, his left shirt collar is sticking up over his coat. It's still up when he puts his hands to his head, but is tucked neatly back in in the next shot, though he still has both hands on his head. A few seconds later, it's the right collar flap that's sticking out instead.

Factual error: The .22 caliber shots would be a higher pitch.
Mr. Monk and the Panic Room - S3-E2
Continuity mistake: Just after the Captain presses the button to open the panic room door, his arms are both down. When it cuts to a shot looking at him from inside the panic room, his left arm is up against the door. (00:14:10)
Mr. Monk and the Panic Room - S3-E2
Continuity mistake: When the Captain and Monk are standing in front of Randy's desk, there is no bag on the table. After a cut, a black bag suddenly appears and the Captain's hands are on it. (00:15:30)
Mr. Monk and the Panic Room - S3-E2
Audio problem: When Darwin is screaming at the bald landlord, his mouth isn't always moving.
Mr. Monk and the Panic Room - S3-E2
Revealing mistake: Throughout the episode, the panic room door is made to look metal. But later when a hole is cut in the door, you can easily tell by looking through the hole that it is wood.
Mr. Monk and the Panic Room - S3-E2
Revealing mistake: In the scene where Darwin and Monk are in the kitchen and Monk calls Dr. Kroger. Darwin pulls the phone out of the wall, but there is no line from the phone to the jack in the wall.
Suggested correction: The phone is a wall type that connects directly at the back. The jack on the wall is wired, and the phone connects when it's mounted. This was a feature of many wall mounted phones as you didn't want exposed wires.
Mr. Monk and the Panic Room - S3-E2
Continuity mistake: Whilst Randy and Sharona are in the kitchen feeding the monkey you can see near the start of the shot that Randy has his right arm leaning against the kitchen counter top. In the next shot his arms are suddenly folded.
Mr. Monk and the Panic Room - S3-E2
Continuity mistake: Darwin the chimp pulls a large blue bowl from Monk's kitchen cupboard and throws it on the floor, breaking it. We cut to a close-up of Darwin spinning, then pull back as he starts pulling out glasses - and the blue bowl is back on the shelf, intact. When the angry landlord enters, Darwin pulls the same bowl from a different shelf and throws it again.
Mr. Monk and the Panic Room - S3-E2
Deliberate mistake: All the dishes that are usually neatly arranged in Monk's kitchen cupboards (pots, pans, stacks of plates etc.) have been replaced here by cheap plastic ware, so that Darwin the chimp can pull them all out and throw them. Though we hear shattering-glass sound effects as they supposedly hit the floor, the dishes Darwin bangs together and throws are very obviously plastic.
Mr. Monk and the Panic Room - S3-E2
Factual error: The cops gain entry to the panic room to be faced with a chimp waving around a loaded handgun, apparently having shot a man, and shrug and make jokes about reading him his rights, instead of expressing the slightest concern that this animal might shoot them. Cops shoot remotely aggressive dogs all the time, but an ape with a gun doesn't even make them raise an eyebrow. Plus the police never did a gunshot residue test on the chimp. Standard procedure, and would've proven they didn't shoot.
Mr. Monk and the Panic Room - S3-E2
Continuity mistake: Stottlemeyer has taken things like a banana and a Monkey Joe out of a black leather bag and places them on a table while interrogating Darwin the chimp. One shot while he's acting like a monkey shows the table's bare and the bag's closed.
Mr. Monk and the Panic Room - S3-E2
Continuity mistake: When Monk gets a glass out of the cupboard, he closes the door. When he picks up the phone, the door is open.
Mr. Monk and the Panic Room - S3-E2
Continuity mistake: When Monk and the Captain are in the recording studio room, the candles next to the framed pictures are lit. When Monk walks past them, they're unlit. They're lit again in the next shot.
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 Blackout - S3-E3
Deliberate mistake: As Monk is using the night vision goggles in his house the lights suddenly come back on and continues on still thinking that the intruder cannot see him. The light coming on should have blinded him or at the very least he should have been able to tell there was more light than before even if he hadn't had much experience using the goggles. All the lights in the house come back on and the amount of light would be too noticeable with night vision. This would have been deliberate as Monk continues to think the intruder still doesn't see him in the dark and is part of the joke in the scene.
Mr. Monk and the Blackout - S3-E3
Continuity mistake: When Sharona is trying to comfort Monk after he gets off the elevator, she's holding his hand and rubbing his arm. When Michelle walks away, in the next shot, Sharona's hands are on Monk's chest and shoulder.
Mr. Monk and the Blackout - S3-E3
Continuity mistake: When the second bomb is being placed (after the restaurant scene), the bomber is holding the bomb by the ends (the short side). In the next shot it's being held by the front (the long end).
Plot hole: While convenient to the plot, the computer system used by the medical examiner is far too poor to be taken seriously for a high level agency. While Monk is unaware of deleting the files on the computer, why would there be a one button push to delete all the files on working cases? Even to not have some sort of password to delete files is questionable, as most systems in offices and workplaces will only have functions like this for administrators, executives etc. We find out that all the files are backed up and are slowly being recovered. However, these types of systems are primarily for emergency scenarios such as fire, flooding and so forth. With the ease that Monk is able to delete the files by accident, it seems a bit hard to believe how easy it is to do.
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.
