Continuity mistake: While at the crime scene in the junkyard, Monk is trying to explain things, but is unable to concentrate because one of the stacked junked cars still has a headlight in it. Frustrated, the Captain shoots the light out so Monk can continue, but as the screen pulls back the headlight is still unbroken in the car.
Continuity mistake: In the flashbacks of Sharona's uncle's fall, he's lying perpendicular to the steps, but in the photos of the incident we saw earlier, he was lying in line with them. In fact in the last flashback showing the murder his position changes again, turning from a 90 degree angle to be more like 45.
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.
Continuity mistake: Monk identifies the kidnappers' house by the pizza box outside by the bin. In the wide shot it's upside down on its corner, with "zza" just visible behind a black bag. In the closeup it's turned around, so we can see more letters, and it's moved.
Continuity mistake: Stottlemeyer says "does that make any sense to you?" as Monk is straightening the pots on the mantelpiece - all the lid handles are horizontal. The camera cuts away for a second, cuts back, and the lid on the far right has suddenly rotated 90°, whereupon Monk straightens it to be horizontal like the others.
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 Monk and Al are sitting to drink wine, Al grabs his bottle with one hand to pour the wine and the other hand is hanging down to his side. In the next shot, as he's pouring the wine, he's holding the glass with the other hand. In the next shot, his hand is by his side again.
Continuity mistake: When Monk is talking to Daniel on the radio, in the shots from inside the truck, Krystal is standing next to the open door, to Monk's left when he turns to face her. In the shots from outside the truck, Krystal is now away from the door and to Monk's right.
