Mr. Monk and the Red Herring - S3-E10
Continuity mistake: In the pet store, the bird's cage has a plastic covering on the sides. But in various shots, either one or both coverings are missing.
Suggested correction: This is wrong, it was just the way the camera angle made the cage appear where I couldn't differentiate the space between the bars, so it looked like there must have been a covering.
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.
Stupidity: It makes no sense why the staff or the guests would serve the wine to Natalie from where the dead body was being stored. The guests and staff go about cleaning up after he died to avoid any trace of him ever coming to the winery including putting his body in a large wine crate. Yet Natalie makes the discovery that the weird smell (of aftershave) from the wine which leads to the police discovering the body. There is no reason to serve her that wine. It was a vineyard after all - they had plenty of wine and as the staff was in on it, they could have made that crate inaccessible to serve. (00:18:35 - 00:40:04)
Suggested correction: The guests and staff involved had nothing to do with which wine was being served. Sylvia was just a hostesses and Ricardo was just a waiter. They happened to dump the body in a cask of the new wine which was being taste tested. The wine expert, bartender, and other waiters weren't involved and didn't know there was a dead body in the cask.
Mr. Monk Is on the Run (2) - S6-E16
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)
Suggested correction: The article being there that fast is a bit odd, the sheriff mentions a police alert had been put out and was why he went to the morgue. That was what he was confronting the captain about. Even without the article the point of why he didn't check is still a valid question.
Do you really believe that the police alert did not include a description of said corpse being found for the missing person's unit to combine against their lists?
Mr. Monk and the Wrong Man - S6-E8
Stupidity: Instead of Monk pounding on the church's inner glass door for someone to let him in, he could have simply used the door handle on the outside which is the same as on the inside. (00:27:30)
Mr. Monk and the Red Herring - S3-E10
Audio problem: In the last line of the episode, the end of the word "spider" that Natalie is saying is cut off. It sounds like "spi." (00:42:05)
Suggested correction: I just watched the scene and I hear the whole word "spider."
Mr. Monk and the T.V. Star - S2-E12
Plot hole: Unless I missed something, the killer didn't wipe his prints off the knife he used to kill his ex-wife.
Mr. Monk Goes Back to School - S2-E1
Continuity mistake: Mr Monk completes his name on the chalk board at the beginning of class, but when class is dismissed the 'k' in Monk is incomplete.
Suggested correction: After he wrote his name, he says "what's up with that k?" and erases it. He started to re-write the k when he got hit by the eraser, leaving it unfinished.
