Mr. Monk is Someone Else - S8-E4

Mr. Monk Makes the Playoffs - S7-E13
Revealing mistake: 7-13, "Mr. Monk Makes the Playoffs": The supposedly live stadium crowd outside Bob Costas' press box is a noticeably fake photo-backdrop. Not a single "person" in the multitude of thousands is moving. (00:40:10)

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.
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 Is on the Run (2) - S6-E16
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.

Mr. Monk's Favorite Show - S8-E1
Revealing mistake: The car that explodes isn't sitting in a striped parking lot space. In fact, it's very obviously parked out in the middle of the lot's traffic lane, well away from any other vehicles, precisely because the special effects crew are about to blow it up.
Mr. Monk's Favorite Show - S8-E1
Continuity mistake: Near the end when Monk is doing his usual "Here's what happened" speech, he hands an envelope to the dad. A few minutes later he walks away from the dad, who still has the envelope in his hand. Immediately, the shot changes and Monk, who is not near the dad, has the envelope.
Mr. Monk and the Magician - S7-E15
Continuity mistake: "Mr. Monk & the Magician": While Monk and Natalie talk to the magician's assistant, the white rabbits in the hutch shift positions instantly with each change of camera angle. (00:20:00)

Continuity mistake: When Van Rankin shoots his wife, the black gym bag, which has been slung over his shoulder since he entered the kitchen, disappears between shots. (00:31:05)
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)
Mr. Monk Goes Camping - S8-E12
Audio problem: At the beginning of Season 8 Episode 12, the round analog dial clock on Monk's nightstand beeps like a battery operated digital travel clock would, and Monk looks over at it. But in Season 8 Episode 16 (at about 38 minutes), that very same clock has a bell type ring that one would expect of a wind up analog dial type clock. (00:01:00 - 00:38:00)
