Mr. Monk and the Astronaut - S4-E14
Plot hole: The murderer mails a garage door opener with the button taped down to his victim and kills her by remote. But A) With the switch continuously in the "on" position, the battery would die long before the package arrived, and B) Door openers use special frequency tones that are set much like a safe combination. The likelihood of one control opening 3 different doors in the same area, as it does here, is virtually nil. (00:33:30)

Plot hole: There is no drug in the world that could render a healthy adult unconscious for two days with a single dose, but let's go with the dramatic licence and allow that there is. Any such drug would be instantly detectable in any one of a dozen toxin screens carried out during an autopsy, and isn't someone going to wonder how a comatose woman hanged herself?

Plot hole: The whole plot hinges on Steve Wagner knocking the victim out for 2 days, remotely hanging her while he's in space, then removing the hanging machine when he lands. But keeping someone unconscious chemically for 2 DAYS is a hell of a feat. And unpleasant though it is, she'd be voiding her bowels over those 2 days, leaving a serious mess, plus all the chemicals necessary to keep her unconscious would be found in an autopsy.

Factual error: During their examination of the crime scene, neither Monk, Stottlemyer, Sherona, Randy or anyone else in the room wear gloves or any kind of other protective clothing. They handle artefacts that could be critical to an investigation of the woman's death, including a cheque made out to her, and they hopelessly contaminate them by doing so.

Continuity mistake: When the captain receives the victim's phone record (outside at the neighbor's house) he calls a number on the bill. But the phone starts to ring (on the other end) before he presses the last digit.

Continuity mistake: When the Astronaut is talking to the kids in the classroom, the position of his arms changes from by his sides to folded between shots.

Continuity mistake: When Steve Wagner gives the class red laser pointers, he tells them to pass them back. The girl on the far right of the shot turns around. When the shot changes, she begins to turn around again.
Mr. Monk Goes to the Dentist - S4-E15
Continuity mistake: When the Captain and Randy are talking in the garage, in the shots over Randy's shoulder, the pad on his guitar strap is over his shoulder. In the shots from behind the captain, the pad is behind his back and can't be seen. (00:24:40)
Mr. Monk Goes to the Dentist - S4-E15
Continuity mistake: When Monk has been chloroformed in his home and is gradually sliding down the doorframe, the dentist's assistant's hands go from being clasped under her chin in one shot to by her sides in another.
Mr. Monk Goes to the Dentist - S4-E15
Continuity mistake: When Randy is at Monk's place talking about hiring him, Monk says "Like who?" to which Randy replies "Like Me". While Randy says this he is holding a glass with one hand, the other being in his pocket. In the next shot, when Natalie says "Is it about the dentist?", Randy is holding it with two hands. Then, in the next shot, he is holding it with one hand again.

Character mistake: He extracted the wrong tooth. He states 3 is the problem, then goes to the other side (left), which would be tooth 14.
Mr. Monk Gets Jury Duty - S4-E16
Continuity mistake: In the jury room, the two windows behind Monk have venetian blinds, which are raised halfway on the right window. But in several shots of the science teacher coming over to identify the white powder, the right window's blinds are pulled down. (00:35:00)
Mr. Monk Gets Jury Duty - S4-E16
Continuity mistake: When the man with the letter from the Attorney General is telling Stottlemeyer not to 'screw it up', he is moving the letter in his hand. However, every time we see Stottlemeyer front on, there is a corner of the letter in the shot, and the letter remains stationary even while the other agent is moving it.
Mr. Monk Gets Jury Duty - S4-E16
Factual error: Since Monk has OCD it would be highly unlikely for him to be on a jury. Plus, Monk works for the police department and since he technically works in the criminal justice system, that would have made him exempt from jury duty.
Suggested correction: First, he would have to ask for exemption in writing prior to serving, with proof, regarding hardship for his OCD. While it's possible his doctor might say serving jury duty would result in physical harm due to his mental illness, it's unlikely to be given by Dr. Kroger. And Monk is not an active peace officer, so that wouldn't earn him an exception.
Mr. Monk Gets Jury Duty - S4-E16
Factual error: When Natalie hears the jury's muffled screams inside the locked room she uses the fire extinguisher to tear off the door knob. But a locked door without a knob is actually only harder to open, because like that you cannot turn the mechanism even if it was unlocked.
Mr. Monk and the Actor - S5-E1
Continuity mistake: During the rehearsal, David, playing Monk, rearranges all the items on the coffee table. But each time the camera angle reverses, the items change positions all by themselves, even when he's not touching them.
Mr. Monk and the Actor - S5-E1
Continuity mistake: The yellow-globed lamp on the movie set is hanging crooked when the actor playing Monk enters. He touches it, but doesn't move it at all, yet in the next shot, it's hanging straight. A few shots later, it's crooked again.
Mr. Monk and the Actor - S5-E1
Continuity mistake: At the end, when Monk is in Dr. Kroger's office, when he says "it's nice to be home", you see Dr. Kroger putting on his glasses. When the camera angle changes, he's putting his glasses on again.
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.
Mr. Monk and the Garbage Strike - S5-E2
Continuity mistake: The edition of the San Francisco Chronicle with the headline on Jimmy Cusack's death is dated April 1, 2006. However, at the end of the episode, which is a few days later, the newspaper with the front page photo of Stottlemeyer arresting Ron Neely, is dated March 24, 2006. In addition to the fact that the date of the arrest is a full week before the date of the murder, April 1, 2006 fell on a Saturday, when the episode says the murder was on a Monday night.
