Mr. Monk Takes His Medicine - S3-E9
Visible crew/equipment: When Monk is talking to the two patrol officers about the suicide and walks down the street, the backlot trailers and equipment are visible around the corner of the building and you can also see a set golf cart. This is supposed to be the street that the shooter and biker drove down earlier in the episode. (00:07:13)
Mr. Monk Goes to Jail - S2-E16
Factual error: Death row prisoners cannot donate organs. No doctor participates in an execution and after the lethal injection the medical examiner must wait at least fifteen minutes to test for cardiac activity before pronouncing the prisoner dead. This is enough time for hypoxia to render the heart, lungs and kidneys useless for transplant. Apart from this, organs intended for transplant must be removed within minutes of the death of the donor. Prisoners are not executed in operating theatres.
Continuity mistake: They interview Jimmy Belmont in prison, who complains how Monk sent him there for killing Randy's uncle in 'Mr. Monk Visits a Farm.' However, in that episode, Monk tricked everyone (including Randy) into believing Randy had solved the murder.
Mr. Monk and the Employee of the Month - S3-E7
Audio problem: There is a high-pitched feedback noise that is only audible every time one particular camera is being shown during this scene. (00:10:35)
Mr. Monk and the Astronaut - S4-E14
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?
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 Billionaire Mugger - S1-E7
Continuity mistake: When Sharon asks Sydney's old flame about the mugging 20 years ago, the glasses in front of them are full when they are being filmed from behind Sydney's ex, then are half empty being shown from behind Sharon, and in the next shot they are full again. (00:32:00)
Mr. Monk Gets Lotto Fever - S7-E3
Factual error: Since Stottlemeyer is accused of being involved in the lotto fraud he would not be allowed to take this case himself.
Mr. Monk Gets Hypnotized - S7-E8
Factual error: At the start of the episode, there is a double rainbow in the sky - both in normal order, while in fact the top rainbow should be mirrored.
Mr. Monk and the Sleeping Suspect - S2-E7
Continuity mistake: When the bomb lands in Sharona's arms it's opening faces towards her. But in the next shot it faces away from her although the motion detector was set to detonate the bomb at the slightest movement.
Mr. Monk Goes to Jail - S2-E16
Plot hole: It is unrealistic that a prison cook who did not punch out would not be missed or found until the next day, especially after a lock-down scenario as portrayed in this episode, where a meal has been poisoned - likely in that very kitchen.
Mr. Monk Goes to the Asylum - S1-E6
Continuity mistake: The doctor says that Mr. Monk is allergic to tomatoes. In another episode Mr. Monk makes a sandwich with tomato. There is another episode in which Mr Monk is excited about square tomatoes.
Mr. Monk and the Genius - S7-E2
Factual error: On the chessboard, both kings are in check, which is an impossible position in chess. (00:15:40)
Mr. Monk Goes to Jail - S2-E16
Factual error: There are a number of unrealistic situations portrayed inside the prison: 1) An inmate scheduled to be executed in less than an hour would not be left so unattended as to require the trustee to yell for help when he went into distress, or to allow the inmate and trustee to exchange objects. 2) A chronic rule-breaker like Spyder, who had just "put a guy's head through a wall," would not have gotten just one day in solitary confinement with no other loss of privileges. 3) The neo-Nazis would not be allowed to wear swastika lapel pins. 4) Death row inmates are not served their last meal by unescorted fellow prisoners.
Mr. Monk and the Astronaut - S4-E14
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.
Mr. Monk Gets Cabin Fever - S3-E12
Audio problem: At the start, the car stops at the gas station (weirdly far from the pumps, for a start). Grooms talks to Monk then walks to the back holding the nozzle, stretching the hose taut, despite no filler cap on that side of the car. We cut to Monk, and we hear a clunk of Grooms attaching the nozzle (to what?). Later Grooms is still holding the nozzle, and as Monk goes inside Grooms is just wandering around aimlessly holding it.
Mr. Monk and the Very, Very Old Man - S2-E5
Continuity mistake: When his wife visits Stottlemeyer in his office he fills the running waterfall with coffee, but later in that scene when he holds her hand to promise her that he will investigate the the old man's death the waterfall is empty again. (00:04:40 - 00:07:10)
Mr. Monk's Other Brother - S7-E10
Other mistake: During gunfire exchange, Jack's gun locks back, indicating it is empty. He then fires 2 more shots out of an empty gun. (00:37:20)
Mr. Monk Goes to the Bank - S6-E12
Factual error: An intelligent, experienced police officer like Stottlemeyer would know perfectly well that shooting a lock will not open it – that's purely a Hollywood myth. Not only would shooting the lock probably jam it, but the ricochet in a closed room like a bank safe could easily kill someone.
Mr. Monk Goes to the Bank - S6-E12
Factual error: Banks never use combination locks. A four-digit lock, like the one used here, would take a patient thief about six hours to open by trying every possible combination, and banks really do take such unlikely scenarios into account. The wall panel in the bank would be secured by two padlocks, with no one person holding both keys.
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.
