Mr. Monk and the Employee of the Month - S3-E7
Audio problem: There is a high-pitched feedback noise that is only audible every time one particular camera is being shown during this scene. (00:10:35)
Character mistake: Stottlemeyer says that the human finger was "still bleeding, freshly severed." But prior to him saying this, when we are shown the finger, there is no bleeding whatsoever and the blood on the severed end had already dried.
Mr. Monk Gets Stuck in Traffic - S3-E13
Continuity mistake: The murderer picks up the victim's cell phone and puts it in front of his cell phone. Then later in the flashback the murderer had in the truck he puts the cell phone behind his own cell phone.
Mr. Monk Gets Cabin Fever - S3-E12
Audio problem: At the start, the car stops at the gas station (weirdly far from the pumps, for a start). Grooms talks to Monk then walks to the back holding the nozzle, stretching the hose taut, despite no filler cap on that side of the car. We cut to Monk, and we hear a clunk of Grooms attaching the nozzle (to what?). Later Grooms is still holding the nozzle, and as Monk goes inside Grooms is just wandering around aimlessly holding it.
Mr. Monk and the Red Herring - S3-E10
Continuity mistake: When Natalie puts out the fire with the extinguisher, the nozzle is still pushed down when she uses it, but when she puts it on the table, in the next shot the nozzle is fully extended. There are a number of times during the scene, when Monk is trying to figure out how to use it, where the nozzle's position keeps changing between shots.
Mr. Monk and the Game Show - S3-E8
Continuity mistake: Whilst Monk is being introduced to the long standing winner on the show a stagehand is adjusting the microphone on his jacket with both hands. As he says "Are you almost done?" the shot changes and the stagehand is just using his left arm to adjust it. The stagehand then pulls his arm away but the next shot he is adjusting the mic again and using both hands to do it. It keeps changing throughout the rest of the scene.
Mr. Monk Takes His Medicine - S3-E9
Visible crew/equipment: When the armored car is being robbed, the camera pans to the left just before Highsmith is about to kill the driver. During this pan, the reflection of the cameraman is visible on the side of the armored car.
Mr. Monk Takes Manhattan - S3-E1
Continuity mistake: In the scene where the two guys are playing chess, the guy with the black hat knocks over the chess pieces after losing. He then starts scrambling up the pieces and leaving his hands near the chess board. When the shot changes to a wide shot of Monk walking away the guy suddenly has his hands on his head.
Mr. Monk Meets the Godfather - S3-E5
Continuity mistake: In the scene where Monk meets Salvatore Lucarelli (Philip Baker Hall), Lucarelli is cutting up fisheads on a cutting board. Throughout the scene the fish on the table constantly change between shots. One of the notable changes is when Lucarelli is discussing the case he has for monk there is a shot of a fish, and when the shot changes you can now see the fish's head has all of a sudden been chopped off.
Mr. Monk and the Red Herring - S3-E10
Revealing mistake: When Julie's teacher is searching the name 'Larry Tilburn', he isn't typing into a search engine, virtual encyclopedia, or anything of the type, the computer just shows a blue screen with a popup message in the middle.
Mr. Monk Gets Stuck in Traffic - S3-E13
Factual error: Monk inspects the wrecked VW Beetle and notes that "the air conditioning is off." But it's a standard 1973 VW: they didn't come with A/C, and though you could add it, it tended to overstress the little air-cooled engine. Look closely and you can see that this VW does not have the bulky under-dash compressor needed to run an add-on A/C.
Mr. Monk Gets Cabin Fever - S3-E12
Factual error: Randy calls the cabin and gets a "not in service" message. But he should have heard an unanswered ring instead. The FBI agent tore the cord from the wall, which in the US does not generate a "not in service" recording. That only occurs when the phone company cuts off your service due to non-payment or cancellation. (00:30:00)
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.
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 Gets Cabin Fever - S3-E12
Continuity mistake: After Stottlemeyer says "Well I'm gonna make the most of it" (when he is talking to Monk in the backyard of the cabin and Monk is cleaning) he looks a little to his left and opens a beer can while his mouth is shut. In the next shot he is looking in a different direction and is smiling a toothy grin.
Mr. Monk Gets Stuck in Traffic - S3-E13
Continuity mistake: In the beginning of the episode when Ray Galardi is meeting with Steve Marriot the amount of sun between shots constantly changes between shots. One moment that is very noticeable is a shot of just Ray with the hill in the background and a lot of shade. After showing Steve it goes back to Ray and the sun is now very bright.
Mr. Monk Gets Stuck in Traffic - S3-E13
Continuity mistake: Whilst Monk is talking with Natalie and Julie about halfway through the episode, Natalie asks Monk whether he helped Julie to find somewhere to go to the bathroom. When Julie says she has managed to hold on Monk says, "isn't she a trooper?" and is pointing his finger at her and then lowers his hand. In the next shot showing Natalie and Julie, he is still pointing at them. (00:21:55)
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 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.
