Deliberate "mistake": When Monk is first teaching his class, the class goes for less than 10 minutes. Submitted by Blibbetyblip

Continuity: At the school tower murder scene, Randy's coat is buttoned up over his tie, but changes suddenly when Stottlemeyer says, "OK, bring him up." The coat is immediately unbuttoned and open all the way in the very next shot. Submitted by Jean G

Continuity: When Monk is leaving Derek Philby's classroom, he is quite content to just pick up a piece of chalk (with his bare hands) to write on the blackboard, but earlier, he makes sure to use a chalk holder to do this and nearly has a panic attack when he gets chalk dust on himself. Submitted by Blibbetyblip

Other: When Monk is leaving Derek Philby's classroom, he dots the "I" in "REMINDER" on the blackboard. However, the word was in capital letters, so the "I" needn't have been dotted. Monk wouldn't make this mistake. (And the word is written in plain block sans-serif letters, so he's not adding a missing line: he's definitely dotting the capital I.) Submitted by Blibbetyblip

Visible crew/equipment: In the scene where Captain Stotlemeyer is putting one of the large snakes back in the glass container, he turns and the base of his wireless microphone is visible when his jacket gets bunched up.

Continuity: In the cemetery scene, Stottlemeyer approaches the grave of the 17 year old open case hit and run victim. The dates on his grave are 1980-1997. But in Dennis Gammill's confession letter in the end, it says he killed the boy in December 1998.

Factual error: When Stottlemeyer backs up the video tape at Monk's house, we can hear the sound chattering backwards. Only a huge industrial (studio) machine would do that. Little home VCRs, like Monk's, mute the sound during in-play rewind and fast forward modes. (Time) Submitted by Jean G

Continuity: When Monk spills the potted plant and grabs a vacuum cleaner from the hall, he's holding the handle with several large paper towels. When he plugs the vacuum in, he now has a wipe in his hand instead. When he's finished plugging in and turns around, the wipe has vanished and there's nothing in his hands or on the vacuum. But when we cut to a wider shot as he turns the vacuum on, the paper towels reappear on the handle. Submitted by Jean G

Deliberate "mistake": All the mail bombs are delivered in packages tied with knotted string. The USPO hasn't allowed string-tied packages since the mid-90s (they get caught in automated equipment), but since the knots were crucial to ID-ing the suspect in this episode, that fact had to be ignored. Submitted by Jean G

Continuity: Dexter places the sapphire necklace on Amber at a completely crooked angle. When the shot cuts, though, it has instantly straightened and centered itself. Submitted by Jean G

Other: In the scene where Mr.Babcock is murdering the woman in the cinema, we see the woman has a big bucket of popcorn. As he starts strangling her, only a small amount of popcorn falls out. When the camera turns toward the floor there is a lot more popcorn on the floor and it it is spread right across the screen.

Deliberate "mistake": When Sharona spots Disher's personal ad in the newspaper, there is a shot of it. She then reads the description of him from the ad, which matches what's on the screen, however, the second part she reads, "Seeks petite blond with no-nonsense attitude, kids ok" is not in the ad shown. (Time) Submitted by Captain Defenestrator

Continuity: When Monk says "I can bench 200", you can tell he has his arms by his sides, but in the next shot, his hands are held up at the level of his waist. (Time) Submitted by Blibbetyblip

Factual error: In this episode, when Sharona and Monk arrive to visit his brother, they talk about the swing set. Monk tells Sharona that his father put up the swing when he was 8 years old but this is a much newer swing set. Look at the curved plastic seats: these have come about in the last six to eight years. It also doesn't look at all rusty like a 40 year old swing would.

Continuity: The blood stains on Brad Terry's sweatshirt change positions after he runs back into the house. A few shots later, they're suddenly so faint they're barely visible at all anymore. Blood stains don't fade, at least not in just a few minutes. Submitted by Jean G

Continuity: In this episode Randy is allergic to cats, in fact he has an allergic reaction even if a cat has been there lately but is not there now. But in Mr. Monk and the Sleeping Suspect, during the scene where Monk and the police are investigating the woman's destroyed house, a cat passes within a few feet of Randy, who doesn't sneeze or show any signs of his allergy. Submitted by Blibbetyblip

Factual error: The SFPD fails twice to trace the kidnapper's call because he isn't on the line long enough. This is an erroneous holdover from really old movies and the days before digital & computer technology. Phone calls have been instantaneously traceable since the 1970s. There's a line tossed in claiming that they need 45 seconds if it's a cell phone, but this is still bogus: cell phone calls are also instantly traceable. Submitted by Jean G

Continuity: In the scene where Sharona returns the dog, she opens the gate, turns around and closes & latches the gate. They even make a point of showing the latched gate before she is on the porch. As she is talking to the owner, you see the gate behind her open and then closed between shots. She had latched it, so all scenes should have shown it latched.

Continuity: In the pre-credits sequence, when Glenne and Ted are fighting, Glenne attaches a clip to the right side of his shirt, but a few seconds later, there is none on his right side. They are all on his left side. They also disappear and reappear.

Visible crew/equipment: When Ted Levine and Glenne Headly are fighting in the pre-credits sequence, a crew member is visible in the car's side window in the left of one shot.
