Mr. Monk Goes to the Office - S4-E4
Continuity mistake: When Monk is trying to join the two cops' conversation about football, in the shots from the side of the police car that they're standing near, the two cops are standing less than a foot apart. In the shots from the other side of the car, they're far apart enough for Monk, Natalie, and Captain Stottlemeyer to stand between them. (00:03:00 - 00:05:00)
Mr. Monk Makes A Friend - S5-E11
Continuity mistake: Monk leaves his front door standing open in anticipation of his new friend's arrival. No one goes near the front hall, but when Hal gets there, he lets himself in by opening a door that has somehow closed itself. (00:10:30 - 00:11:50)
Mr. Monk Gets Jury Duty - S4-E16
Continuity mistake: In the jury room, the two windows behind Monk have venetian blinds, which are raised halfway on the right window. But in several shots of the science teacher coming over to identify the white powder, the right window's blinds are pulled down. (00:35:00)
Mr. Monk and the Leper - S5-E10
Continuity mistake: In the final scene, the pillows on Natalie's couch keep shifting positions between shots, from straight to crooked and back again. (00:40:30)
Mr. Monk Joins a Cult - S6-E11
Continuity mistake: At the end, the grocery bags Natalie carries change shape and orientation several times during Monk's confrontation with "Father." (00:41:00)
Mr. Monk and the Red Herring - S3-E10
Continuity mistake: Monk empties a pocketful of pushpins onto the science teacher's counter top. One rolls to the very edge, separate from the others. A few minutes later, the stray pin is missing. Just before Monk and Natalie leave, however, it reappears on the counter edge.
Mr. Monk Goes to Vegas - S3-E14
Continuity mistake: After Monk tells Randy to hit whilst playing Blackjack, the dealer gives him the Three of Spades. The dealer places it a bit to the right and over the Eight of Spades. The next shot we see of the cards the Three is now completely over the Eight and we can only see a bit of the bottom of the Eight.
Continuity mistake: In "Mr. Monk and the Birds and the Bees" Natalie mentions she doesn't have a sister when Julie's "boyfriend" says the aunt hired him to break her and her real boyfriend up. Here she has a sister and a niece.
Suggested correction: Natalie doesn't have a sister in this episode. The woman seen is credited as "Aunt Teresa." They're most likely cousins. Children of cousins are often referred to as nieces/nephews. This would make Natalie "Aunt Natalie" to Anne Marie (and Teresa would be "Aunt Teresa" to Julie).
Mr. Monk and the Employee of the Month - S3-E7
Continuity mistake: When the episode begins, the Employee Of The Month is shown walking into Mega-Mart. The exterior of the store is shown as a cement color and there is a garbage can right beside the front door of Mega-Mart. When the Employee Of The Month is shown opening up the door to the store, just seconds later, you will see the exterior of the building is now yellow and white and there is no longer a garbage can beside the door. Clearly they are using two completely different buildings. (00:00:40)
Mr. Monk Gets Cabin Fever - S3-E12
Continuity mistake: When Randy and his 'girlfriend' are having take-away (take-out) food, the girlfriend says, "Before he died, he said he's always look out for me". As she says this, her arms are resting on the table, but in the next shot her elbows are on the table and her hands are together just under her chin.
Mr. Monk Is on the Run (1) - S6-E15
Continuity mistake: The needle Monk finds in the campers' sewing kit threads itself instantaneously between takes. He finds the spool of orange thread, and in the very next shot, tho there's absolutely no indication of any time passing, he's holding the already-threaded needle. (00:22:00)
Mr. Monk and the Three Julies - S6-E13
Continuity mistake: In the police station, Julie's hair is neatly combed over her left shoulder. Then it's disarrayed and partially falling over her right shoulder, too. Then it's neat and only on the left side again. (00:27:45)
Mr. Monk and the Three Julies - S6-E13
Continuity mistake: The damage to Stottlemeyer's new car doesn't remain consistent from shot to shot. The dents change configuration and the angle of the torn fender also changes. (00:40:15)
Mr. Monk and the Garbage Strike - S5-E2
Continuity mistake: When Captain Stottlemeyer's car stops, he pulls to the side of the road into a cluster of garbage bags, which are lining the entire road. When Natalie approaches the car, there are only a few bags on the curb next to it and the rest of the street is clean. (00:33:00)
Mr. Monk and the Class Reunion - S5-E6
Continuity mistake: At the start of the episode, when Katherine Rutherford is killed, she lands on her stomach with her eyes wide-open. Yet when Stottlemeyer and Disher arrive and see the cops looking at the body, she is now lying face-up and her eyes are closed. It is hard to believe that the police would move the body that much without first marking its original position with tape.
Suggested correction: It's a TV and movie trope that cops outline a body with tape or chalk, that's what photographs are for. But if someone found an old lady lying on her stomach, especially without blood, they might roll her over to check if she's OK or could be resuscitated.
Mr. Monk and the Actor - S5-E1
Continuity mistake: At the end, when Monk is in Dr. Kroger's office, when he says "it's nice to be home", you see Dr. Kroger putting on his glasses. When the camera angle changes, he's putting his glasses on again.
Continuity mistake: When Monk is asking Ms. Moody if the roof is known, she's crying into both her hands. But in the next shot, she's only crying into her left hand and her right hand is down. The shot changes, and we see her lowering her right hand, not left. In the next shot her left hand is up again.
Continuity mistake: In the beginning, we see Cassie with her watch on her left wrist. But in the shot with both her hand on Joseph's back, the watch is on her right wrist.
Mr. Monk Is on the Run (2) - S6-E16
Continuity mistake: When Monk and Natalie are watching the video of Dale, Monk puts his hand behind the screen (like he's blocking the sun to see it better) and Natalie is holding it on the bottom. When the shot changes to the screen, there're no hands behind it.
Mr. Monk and the Man Who Shot Santa - S6-E10
Continuity mistake: The amount of stuffed animals on Natalie's hood change depending on the camera angle, as she and Monk are talking before he goes up to the roof.
