Mr. Monk Goes to a Rock Concert - S5-E8
Continuity mistake: There are two mistakes when Natalie runs up to Monk after he leaves the port-a-potty. First, notice that when Monk is replying to Natalie's first question, her thumb is sticking out, but it isn't when the shot cuts to a front shot of Natalie. Secondly, as Natalie is leading Monk away, her purse has gone from being over her shoulder to being over her elbow, and back when Monk and Natalie turn to see Stork's body fall out of the port-a-potty. (00:11:45 - 00:12:20)
Mr. Monk and the Really, Really Dead Guy - S5-E15
Factual error: Monk typing the address into his laptop would not affect the trace the agents are doing, it definitely wouldn't pop up on the agent's screen as the result of the trace.
Mr. Monk and the Really, Really Dead Guy - S5-E15
Plot hole: In this episode, Monk doesn't know to open a cell phone to answer it, but in "Mr. Monk and the Kid", he used a cell phone with the ransom drop with no problems. (00:04:25 - 00:05:05)
Mr. Monk Meets His Dad - S5-E9
Factual error: The runaway truck ramp has no advance signage (e.g. Runaway Truck Ramp Ahead 1/2 Mile) as real runaway truck ramps do. It has no loose sand to slow down the truck's wheels. And it doesn't point uphill as a real ramp would.

Mr. Monk and the Class Reunion - S5-E6
Factual error: Stottlemeyer says that if Diane killed herself, her suicide note would go on the public record (and her old nurse would recognize it as a copy of her decades-old note). Since when are suicide notes made public?
Mr. Monk Goes to the Hospital - S5-E16
Continuity mistake: When the police are told room 623 is the geriatric ward, Stottlemeyer is holding the seal with the glove up in his right hand when Randy leaves. But in the next shot, his hand is down and you don't see the glove.
Mr. Monk Goes to a Rock Concert - S5-E8
Other mistake: At the end, when they're putting Kris in the cop car, you can see the car numbers don't match. On the door it's listed as car number "664", but on the roof it's is number "32" something.
Mr. Monk and the Class Reunion - S5-E6
Continuity mistake: In the opening scene, when the woman comes out of the room, you can see the rug in the hallway. But in the next shot, there's two plastic runners over the rug. It alternates from being there to not depending on the camera angle.
Mr. Monk and the Actor - S5-E1
Continuity mistake: When Ruskin and Monk are tussling with each other, the gun falls onto the wipers, with the barrel touching the wiper and handle up. The next time we see the gun, the handle is down and touching the wiper. It keeps flipping back and forth in various shots.

Continuity mistake: During the touch football game, when Natalie first throws the ball to Monk, he catches it and a guy in a blue T-shirt and jeans is running up behind him. Angle switches as Monk twists out of the way, and it's a different guy wearing black shorts instead. A few cuts later and Monk runs past the same guy in black shorts again.
Mr. Monk Makes A Friend - S5-E11
Character mistake: At the crime scene, the #8 evidence marker is in the bathroom. When Monk and the Captain are examining the body, a #8 evidence marker is seen on the lamp. They wouldn't use a number more than once at a crime scene.
Mr. Monk Makes A Friend - S5-E11
Continuity mistake: The position of Gail's body moves at the crime scene from when officers cover her head with the tarp to when the Captain uncovers her a few moments later. At first, her left hand is under her forehead and covered by her hair, but then the hand is away from her head and not covered by hair.
Continuity mistake: When Linda is showing the apartment to the Captain, she has her phone in her left hand and crosses her arms. Her arms stay crossed, but then in a later shot, with her arms still crossed, the phone is in her right hand.
Answer: Notice also that in the opening credits scene when he is touching parking meters her also wipes his hand on his clothes each time he does it.
