Mr. Monk Meets Dale the Whale - S1-E4
Revealing mistake: When Monk is showing how Dale and his Doctor murdered the judge one can see that the knitting of the right chair is already cut to ensure that the policeman will fall through it when he later steps on it.
Mr. Monk and the Leper - S5-E10
Revealing mistake: When the balloon goes over the cliff, a very obvious dummy replaces Monk.
Mr. Monk Goes to a Fashion Show - S4-E10
Revealing mistake: The fan letter Monk wrote to shirt Inspector 8, shown in close-up where it hangs on her work station wall, consists of the same paragraph printed out twice. (00:06:45)
Mr. Monk and the Leper - S5-E10
Revealing mistake: Look at the stuntman who stands in for Tony Shalhoub when the balloon crashes and the basket scrapes and bumps along the ground. He is about fifty pounds lighter than Shalhoub, looks nothing at all like him and his hair looks like a Harpo Marx fright wig dyed black.
Mr. Monk and the Red-Headed Stranger - S1-E12
Revealing mistake: In the scene where a man is streaking, he is carefully made to look naked. But when he is running through the park, there is one shot where you can see some black underwear.
Mr. Monk and the Red Herring - S3-E10
Revealing mistake: When Julie's teacher is searching the name 'Larry Tilburn', he isn't typing into a search engine, virtual encyclopedia, or anything of the type, the computer just shows a blue screen with a popup message in the middle.
Mr. Monk and the Genius - S7-E2
Revealing mistake: While Linda is lying dead on her bed, you can see that she is breathing, in two cut scenes, especially at the moment when Monk says "I don't know."
Mr. Monk and the Panic Room - S3-E2
Revealing mistake: Throughout the episode, the panic room door is made to look metal. But later when a hole is cut in the door, you can easily tell by looking through the hole that it is wood.
Revealing mistake: When Cassie Drake pushes Joseph Moody down the stairs, it is very obvious that the man falling down the stairs is not Jack Carter. His hair is not even close to the same color.
Mr. Monk and the Captain's Marriage - S4-E12
Revealing mistake: In their efforts to hide Gerald's pet mouse from the hospital staff, Randy and Natalie toss the rodent back and forth and alternate hiding him in their pockets. But every time he's tossed, Devo the Mouse gains weight. In fact, Devo's (stuffed?) stunt-mouse double is at least twice Devo's actual size. (00:27:00)
Mr. Monk and the Panic Room - S3-E2
Revealing mistake: In the scene where Darwin and Monk are in the kitchen and Monk calls Dr. Kroger. Darwin pulls the phone out of the wall, but there is no line from the phone to the jack in the wall.
Suggested correction: The phone is a wall type that connects directly at the back. The jack on the wall is wired, and the phone connects when it's mounted. This was a feature of many wall mounted phones as you didn't want exposed wires.
Mr. Monk and the Leper - S5-E10
Revealing mistake: When Monk is hanging from the cliff, in the shots looking down at Monk you can see the ocean through him.
Mr. Monk Makes A Friend - S5-E11
Revealing mistake: During the fight in the kitchen, piles of plates are knocked to the floor. The plates that we see hitting the ground all remain intact. Nevertheless, we hear the sound of plates smashing, and when the aftermath is shown, there is broken crockery everywhere. Clearly the plates used were made of plastic or some other unbreakable substance to minimise injury to the actors and stuntmen.
Mr. Monk and the Wrong Man - S6-E8
Revealing mistake: During the fight between Max and Paulie, the stunt double for Paulie is easy to spot - he has a full head of dark hair, whereas Paulie is gray and largely bald on top. (00:23:30)
Mr. Monk Gets Stuck in Traffic - S3-E13
Revealing mistake: The VW Beetle that slides out of the dump truck and rolls over is noticeably not the same car the victim was driving earlier. It's a lighter color, and is already badly dented, even before it's wrecked.
Mr. Monk Goes to the Hospital - S5-E16
Revealing mistake: When Monk and the others are examining the crime scene, the "corpse" can be seen breathing (his abdomen is rising and falling) and blinking. There are various shots in this scene taken from behind the body looking into the room, and some of these are pulled back so that the body is visible while others are zoomed in so that it is not; this is not a mistake, but suggests that maybe the actor was told he would not be visible in these shots and so did not need to hold his breath.
Mr. Monk and the Daredevil - S6-E7
Revealing mistake: When Monk, Natalie, and Joey are fighting on the roof, the end of the metal pipe in Joey's hand wobbles around a lot, as if the pipe is made of rubber. (00:37:20)
Mr. Monk Is on the Run (2) - S6-E16
Revealing mistake: When Natalie visits Dale in prison you can tell that Dale is wearing a "fat suit". The suit on his arm is folding up on itself like a glove.
Mr. Monk Gets Hypnotized - S7-E8
Revealing mistake: There is an obvious stunt double when Monk is fighting with Sally Larkin for the piece of chewing gum: he is younger, more tanned, and possibly wearing a wig in order to emulate Tony Shalhoub's hair. (00:35:55 - 00:39:05)
Mr. Monk Makes the Playoffs - S7-E13
Revealing mistake: When Monk steps in front of the limo to stop it from leaving, on the bottom right of the screen there's a black line that doglegs to the right (seen over Monk's coat sleeve). It's like the camera was cracked or something was stuck to it. When the camera angle changes it's gone, but is there where the camera is back on Monk.
