Continuity mistake: When Linda is showing the apartment to the Captain, she has her phone in her left hand and crosses her arms. Her arms stay crossed, but then in a later shot, with her arms still crossed, the phone is in her right hand.
Continuity mistake: When Jay pulls up to the marina, he parks at an angle and quickly jumps out and then we see him take off in his boat. When the Captain arrives, Jay's car is no longer at an angle and is parked properly.
Mr. Monk Makes A Friend - S5-E11
Revealing mistake: During the fight scene in the restaurant kitchen you can see that the woman is a stuntman, you can even see the horrible wig pop up off the stuntman's head a few times.
Mr. Monk Is On The Air - S5-E13
Continuity mistake: When Monk and Natalie are getting out of their car at Max Hudson's house, there is a woman on the sidewalk walking past the house. As soon as Monk asks, "What station is he on?" the camera angle changes to a view from Max's porch, and said woman suddenly disappears, when she should be seen walking across the driveway. (00:07:55)
Mr. Monk and the Class Reunion - S5-E6
Continuity mistake: When Natalie is noticing Monk's nickname on his registration form, you can see a female extra with black hair, a gray outfit and a purse on her left shoulder walk past Natalie on the left side of the screen. Twenty seconds later, as Natalie is turning and preparing to walk away, the exact same female extra walks past her again, again going in the same direction. Also, in the same shot, you see a male extra with a satchel over his shoulder walk past the camera as Natalie is pulling the form from her purse, and he briefly and instantly reappears walking past Natalie again at the point where she grins and says, "I don't know!" for the second time. (00:05:25 - 00:06:10)
Mr. Monk Goes to a Rock Concert - S5-E8
Continuity mistake: When Monk and Natalie are first talking to Kendra Frank, when Kendra says,"Look, they're trying to say he OD'd! Okay? That's impossible! He's been clean for 17 months! I know, I talked to him about it every day!" you can see that Monk has his right arm down by his side. But when the camera changes angle to Natalie replying,"Well, Kendra, we were there. We saw a needle in his arm," Monk's right hand goes from being by his side to scratching the side of his cheek with his finger. (00:13:10 - 00:14:35)
Mr. Monk Is At Your Service - S5-E12
Continuity mistake: During the brunch scene with Natalie's parents, the rolls in the bread bowl change position several times. In some shots, there are four, in others, there are five. They also go from being piled on top of each other to being arranged in the bowl and back several times. They're out of Monk's reach, so he's not just "making them even" either. (00:04:50 - 00:06:35)
Mr. Monk and the Big Game - S5-E3
Factual error: All the players have their first names on the back of their jerseys. They should have their last names on the jerseys for better identification considering some of them would probably have the same first name.
Suggested correction: This isn't a mistake just because a school does it a different way than what you expect. Not to mention that some people also have the same last name, so using the last name would create the same "problem." All they would have to do is add a last name initial.
Mr. Monk Meets His Dad - S5-E9
Character mistake: At some point Monk asks his father what the device in the car is. His dad tells him it's a GPS. It's difficult to believe that our detective doesn't recognize the machine, even if it's probably another model: the whole plot of the episode 2x03, Mr. Monk Goes to the Ballgame, revolves around a tampered-with GPS.
Mr. Monk Makes A Friend - S5-E11
Continuity mistake: Monk pushes aside a glass of milk on the table in his apartment. It is mentioned multiple times during the series that Monk is afraid of milk. He would never have any in his home, and certainly wouldn't have a neutral reaction to it. Also, the milk appears to have spilled a little as it was pushed, and yet in the next shot there is no milk on the table. (00:33:00)
Mr. Monk Goes to the Hospital - S5-E16
Audio problem: When Monk is saying "motive" in the phrase "this one had a motive", the word is spliced in two, as they used two different takes and combined them. Very robotic. (00:28:55)
Mr. Monk Goes to a Rock Concert - S5-E8
Continuity mistake: The lighting and position of the sun changes constantly throughout the episode and between scenes. For example, when Monk and Natalie are at the first aid tent, it looks cloudy and the lighting suggests that it is midday. Yet in the very next scene, when Monk, Natalie and Kendra catch up to Stottlemeyer, Disher and Jared, it appears to be sunny and late afternoon/early evening. (00:19:00 - 00:25:05)
