Mr. Monk Gets Stuck in Traffic - S3-E13
Revealing mistake: The VW Beetle that slides out of the dump truck and rolls over is noticeably not the same car the victim was driving earlier. It's a lighter color, and is already badly dented, even before it's wrecked.
Mr. Monk Takes His Medicine - S3-E9
Continuity mistake: In Stottlemeyer's hospital room, a medicated Monk finishes off the leftover pudding from the food tray. Then, while he's talking to them, the pudding smeared on his upper lip disappears and reappears between shots.
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 Meets His Dad - S5-E9
Continuity mistake: When Julie talks to Monk on the phone, her hair is down over her right shoulder but swept back behind her left one. When she hangs up and hands the phone to her mom, the hair is suddenly covering her left shoulder instead, and now her right shoulder is bare. (00:17:15)
Mr. Monk Goes to the Dentist - S4-E15
Continuity mistake: When Randy is at Monk's place talking about hiring him, Monk says "Like who?" to which Randy replies "Like Me". While Randy says this he is holding a glass with one hand, the other being in his pocket. In the next shot, when Natalie says "Is it about the dentist?", Randy is holding it with two hands. Then, in the next shot, he is holding it with one hand again.
Mr. Monk Takes His Medicine - S3-E9
Continuity mistake: During Monk and Sharona's race to the armored car robbery scene, the red Mustang's rear-view mirror disappears. When they arrive, though, it's back in place on the windshield. (00:36:30 - 00:38:30)
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 Three Julies - S6-E13
Visible crew/equipment: At the end, as George is arrested, equipment shadows can be seen moving across Disher's back. In the reverse angles, there's nothing behind him but the window, and nothing's moving in that. (00:38:00)
Mr. Monk and the Red Herring - S3-E10
Continuity mistake: At the science fair, after Lyle Peck lights the poster on fire he puts the Bunsen burner onto the table a little away from its original position but when the camera angle changes it is back where it originally was, under the beaker and stand.
Mr. Monk and the Candidate (1) - S1-E1
Character mistake: When Captain Stottlemeyer is saying that the two murders are unrelated, he says, "He was stabbed, she was shot," when the truth is the exact opposite.
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 and Mrs. Monk - S4-E6
Continuity mistake: When the Trudy impersonator is talking to Janice's father in the diner, the venetian blinds on the window to his left alternate between raised and lowered positions as the shots change. (00:06:50)
Continuity mistake: In the opening sequence, the uniformed cop who finds toddler Tommy holding the severed finger bends down and says, "What've you got there, big guy?" In full shot, the cop is bare-handed. But when we cut to a close-up in the middle of his line, he's suddenly wearing a latex glove.
Mr. Monk and the Naked Man - S6-E3
Continuity mistake: While Monk and co. question Vicky's roommate, two throw pillows behind her on the couch shift their orientations several times from shot to shot. The larger one also moves from the couch corner to a spot behind the woman's left arm and then back again. (00:14:00)
Mr. Monk and the Naked Man - S6-E3
Continuity mistake: A little white pillow on Natalie's couch falls over when Monk gets up, then rights itself again when he's in the kitchen. (00:31:15)
Mr. Monk and the Girl Who Cried Wolf - S3-E6
Visible crew/equipment: Nurse Davis swings open Disher's car door at the end, and captures a reflection of the camera and the entire film crew standing nearby. (00:40:40)
Mr. Monk and the Big Game - S5-E3
Visible crew/equipment: As Monk and Natalie leave the victim's brother's apartment, part of the camera rig can be seen moving across the bottom of the screen. (00:26:20)
Mr. Monk Takes Manhattan - S3-E1
Factual error: The .22 caliber shots would be a higher pitch.
Continuity mistake: In the opening scene, the orange-and-white scarf that Paul Harley uses to blindfold Lorissa changes positions and color patterns repeatedly between shots as he escorts her from the pool to the garage.
Mr. Monk Is on the Run (2) - S6-E16
Continuity mistake: At the end, when Dale Biederbeck is screaming at Monk, Dale is sitting in his wheelchair with both his hands down in his lap. The shot cuts in the middle of his sentence, and suddenly he has one hand up on the cell bars. (00:40:30)
Suggested correction: When he says Adrian is trapped in a worse prison, you see him put his hands on the bar. They're not in his lap.
