Continuity mistake: When Monk is at the hotel, a teenage girl comes in to clean up the room. While they are conversing, the subject of mysteries comes up and she goes out and gets the newspaper and places it in front of Monk on the table. They then talk a little more about it and Monk gestures with his hands for her to take the newspaper away and she then picks up the newspaper off the table and exits the room with it. During this entire sequence, you can see that Monk does not ever touch the newspaper. Later on, at the car wash, Mr. Monk sees a newly-painted red SUV that used to be silver colored. When recalling that the teenage girl said that they were looking for a silver SUV, it now shows Monk pushing the newspaper across the table towards the teenage girl even though he never touched it in the original scene.

Continuity mistake: When Mr. Monk is attempting to turn off the key to the Governor's car, his right hand is clutching the top middle portion of the front windshield. However, one of the next camera shots shows the windowshield only with no hand at the top. Then a couple of camera shots later, Mr. Monk's right hand is now on the top of the dashboard. At the end of the sequence, his right hand is clutching the top middle portion of the front windshield again. (00:36:30)
Continuity mistake: Monk kicks an oil drum across the floor toward Rawlins. In the master shot, it rolls half the distance and passes a black line on the concrete. The angle changes to a view from behind Monk and Natalie as the barrel keeps rolling and almost reaches Rawlins. But when the master shot returns, the barrel is again just passing the midway line on the floor. (00:25:00)
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)
Factual error: When Captain Leland Stottlemeyer looks at the postcard that Mr. Monk sent to him, the address shown is for the city of San Francisco with a zip code of 90019. This zip code is for the city of Los Angeles. The actual zip code for the address shown, after checking with the U.S. Postal Service website, is 94105. (00:07:50)
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.
Plot hole: When Stottlemeyer is confronted by the Sheriff for not going to the morgue there are 2 plot holes in that one scene: first it is impossible for that article to be in the morning paper since the coast guard "just fished him out" last night. And secondly an article, especially a long article like the one about the body in the bay would contain a physical description of said body. That is the reason it does not make sense to even ask the captain why he did not go to check the body to see if it was Monk when the body was tattooed and had red hair. (00:13:30)
Continuity mistake: In Season 6, Episode 16, "Mr Monk Is On The Run Part 2,," Natalie is organising his funeral after Monk is announced dead in the previous episode. She is talking to Randy and says she found a picture of him smiling. You see the photo of Natalie, Adrian and Julie on Christmas Eve. This picture was taken in Season 6, Episode 10, "Mr Monk and the Man who Shot Santa Clause". In the photo you can see the three of them smiling. But when you see the picture taken on Christmas Eve, Adrian is not smiling. He has a disgusted look on his face after he ate a cookie. Also when the picture was taken, Julie was smiling with her mouth closed but in the photo she is smiling with her teeth.
