Mr. Monk and the Class Reunion - S5-E6
Continuity mistake: At the start of the episode, when Katherine Rutherford is killed, she lands on her stomach with her eyes wide-open. Yet when Stottlemeyer and Disher arrive and see the cops looking at the body, she is now lying face-up and her eyes are closed. It is hard to believe that the police would move the body that much without first marking its original position with tape.
Suggested correction: It's a TV and movie trope that cops outline a body with tape or chalk, that's what photographs are for. But if someone found an old lady lying on her stomach, especially without blood, they might roll her over to check if she's OK or could be resuscitated.
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 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 Class Reunion - S5-E6
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 Gets a New Shrink - S5-E7
Continuity mistake: When the cleaning woman's body is found, she's lying on the floor face up. A short time later, despite repeated admonitions that nothing should be or has been touched, the corpse has somehow turned itself over and is now lying face down. (00:02:05 - 00:07:45)
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 Goes to a Rock Concert - S5-E8
Continuity mistake: When Monk and Natalie are first talking to Kendra Frank, when Kendra says,"Look, they're trying to say he OD'd! Okay? That's impossible! He's been clean for 17 months! I know, I talked to him about it every day!" you can see that Monk has his right arm down by his side. But when the camera changes angle to Natalie replying,"Well, Kendra, we were there. We saw a needle in his arm," Monk's right hand goes from being by his side to scratching the side of his cheek with his finger. (00:13:10 - 00:14:35)
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 to a Rock Concert - S5-E8
Continuity mistake: When Kris Kedder is on stage performing "Peggy's Gone to Memphis," notice that his 12-string guitar keeps changing positions between shots. In most of the long shots, he's holding and playing it. In most of the closer angles, it's hanging at his side and he's holding the microphone instead. (00:30:15)
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 Meets His Dad - S5-E9
Continuity mistake: When Julie talks to Monk on the phone, her hair is down over her right shoulder but swept back behind her left one. When she hangs up and hands the phone to her mom, the hair is suddenly covering her left shoulder instead, and now her right shoulder is bare. (00:17:15)
Mr. Monk Meets His Dad - S5-E9
Visible crew/equipment: Jack opens the diner door for Monk, and its glass window panes mirror the camera crew and a big rectangular studio reflector. (00:29:00)
Mr. Monk Meets His Dad - S5-E9
Continuity mistake: Jack's big rig has a huge Christmas wreath on the front grill. When the truck loses its brakes, there's an overhead view of it careening down the road, and the wreath has disappeared. It's back in the next shot, though. (00:34:30)
Mr. Monk Meets His Dad - S5-E9
Plot hole: Monk's dad, Jack, drives an 18 wheeler. In the scene where Jack pulls over to the side of the mountain road so they can discuss specifics about the GPS, a brake line is shown breaking and spurting what I assume is meant to be brake fluid. The rig then rolls down the mountain. However, 18 wheelers don't have brake fluid since they don't have hydraulic brakes, they have air brakes. Even if the rig lost its brakes due to loss of air pressure, the brakes are spring loaded to lock up all the wheels in this case and prevent movement. That's how you set the parking brakes, by releasing the air pressure. In other words, if he has air, he can use his application brakes; if he's lost air, he has his parking brakes set. Rigs that lose their brakes going down steep grades do so due to extreme overheating, causing brake fade, an inability of the brake shoes to grab the brake drums. This wouldn't have happened while they were parked.
Mr. Monk Meets His Dad - S5-E9
Deliberate mistake: In the opening scene, Wood's tie is grabbed by an exposed fan belt located above the side of the engine. However, this belt/pulley assembly doesn't exist in a real truck's engine compartment - the fan belts are all in front of the engine, where the camera can't see them easily. The prop master must have added this dangerous device to the truck to allow the camera to see the strangulation.
Mr. Monk Meets His Dad - S5-E9
Other mistake: When Jack Monk is filling up his truck, the numbers on the pump don't add up right and keep changing. The cost is $3.599/gallon, but in one shot you see the sale price reads $93.78 for 28.348 gallons. The sale price should be $102.02. But in a later shot, he's only pumped 27.126 gallons. Then when he hits $100 sale price, it's for 31.259 gallons ($3.199/gallon) but in the next shot it reads 27.719 gallons.
Mr. Monk Meets His Dad - S5-E9
Continuity mistake: When Monk is looking through the boxes on the trailer, on the first shot, the box marked "Tucson" isn't flush with the box underneath. But after, it's flush without anyone touching it.
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 Meets His Dad - S5-E9
Visible crew/equipment: When Monk and his dad pull over to a diner there are visible feet behind the truck.
Mr. Monk Meets His Dad - S5-E9
Character mistake: At some point Monk asks his father what the device in the car is. His dad tells him it's a GPS. It's difficult to believe that our detective doesn't recognize the machine, even if it's probably another model: the whole plot of the episode 2x03, Mr. Monk Goes to the Ballgame, revolves around a tampered-with GPS.
