Continuity mistake: When Monk takes the dog to the park, they're standing on the curb by the grass when he goes to take the leash off. After he says "get ready", the shot changes and they're not by the curb anymore. They're back on in the next shot.
Mr. Monk and the Sleeping Suspect - S2-E7
Character mistake: Brian Babbage is such a perfectionist and plans out such an elaborated plan for his crimes that it is very unlikely that he would simply leave the ketchup bottles sticking to the ceiling for the police to be found after he had timed the perfect glue for his plan. Plus, he even had staffers who already knew about the bottles and it would have taken him not more than a single order for the bottles to be removed. (00:23:50)
Mr. Monk and the Daredevil - S6-E7
Continuity mistake: When Natalie's fighting with Harold's cousin on the roof she loses her shoes. A shot later, and they're back on her feet.
Mr. Monk and the Daredevil - S6-E7
Revealing mistake: Watch as Natalie fights with Harold's cousin on the roof. The same shot where she's barefoot, she's also got thicker hair, indicating a wig on a stunt double.
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.
Happy Birthday, Mr. Monk - S8-E9
Character mistake: Given how Monk is it seems unlikely he'd forget about being in a dumpster filled with garbage and be able to enjoy a birthday party, even if it's his own.
Mr. Monk and the Lady Next Door - S7-E12
Audio problem: Two words near the beginning of Monk and Marge's dinner conversation are audibly spliced. When Marge says "what does a", the word "a" is cut off at the beginning; and when Monk says "detective does" in his response, the end of the word "does" is cut off during the s. (00:15:15)
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 Three Julies - S6-E13
Plot hole: There is no other reason for Randy to hand Natalie the walkie-talkie but to fill that plot hole. He is in fact in breach of police rules when he hands his department issued radio to a civilian to answer it while he is on duty. The same goes for Stottlemeyer and the car keys he hands to Monk. Even more so since he knows Monk could not even drive that car to the side in the far fetched scenario that a police car had to be moved while the cop is serving a warrant inside the building the car is parked in front of. (00:01:15)
Mr. Monk and the Airplane - S1-E13
Factual error: Though anti-freeze is lethal it does not kill quietly and fast but rather agonizingly, painfully and slowly, inducing vomiting and fever. (00:30:30)
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.
