Continuity: In the episode when Gus and Shawn have to become teachers at a school to solve a murder, when they are talking to the two kids outside of the school for the first time, one of the kids has a juice box. Shawn starts talking and it shows from behind the one kid with the juice box and he is about to take a sip, then the shot changes and the juice box is by his side.

Visible crew/equipment: When Shawn and Gus gets out of the car at the Mausoleum Parking, you can see the camera man reflected in the mirror inside the car.

Visible crew/equipment: S01E13 - "Game, Set. Murder?". When Shawn and Gus runs out of the crime scene apartment, heading for the restaurant across the street, you can see the camera and a crew member sitting on a chair reflected in the mirror behind Gus.

Continuity: In the episode "Gus's Dad may have killed an old guy," just before Shawn notices the abrasion on the corpse's scalp, the two men put the man's arm in the body bag and begin to zip it up. They then put the same arm in the body bag again, as the stain on the man's shirt front is shown.

Continuity: In the episode "Gus's Dad may have killed an old guy", the red ball in the first scene changes position. In the close up shot, there is a green plant in front of the ball with two stems. In the next shot (from above) there is no longer a plant on that side of the red ball.

Continuity: In the episode "Bounty Hunters!" in the restaurant, Byrd slamms Tancana's face into a burger and mustard/ketchup smears across the left side of his face and nose. In the echo, the condiments are on the opposite side of his face. After Tancan drops down behind the seat and then reappears, most of the condiments have been removed, but the glob on the left side of his nose is lower and more on the top of his nose than it had been before. (Not a change that would have happened from him rubbing it off and missing some.) The blob continues to migrate throughout the rest of the time they are in the car.

Continuity: When Shaun, Gus, and Nigel are having dinner over at Henry's house, Shaun's plate already has a steak on it before Henry walks in with the first batch. Then, the steak disappears right before Henry plops one on Shaun's plate.

Continuity: In the episode "American Duos," a man attacks the judge by running out of the shower. When he runs through the shower, a shower curtain is draped over him. For most of the scene it is over his head, but when he is dragging the judge into the shower, the curtain has moved off of his head and is even gone completely in one shot, perhaps to make the actor more visible.

Continuity: In the episode "American Dous" when Carlton is talking to the judge, the match in his mouth changes from the left and right throughout the scene.

Revealing: Whenever you see Shawn and Gus outside it appears to be warm but if you look in the background people are wearing jackets and heavy coats, revealing that during filming it was winter and cold out.

Continuity: When Shawn kicks over the carry-on bag at the end, it lands with the handle on top. The subsequent wide shot shows the bag with the handle on the bottom. The handle is back on top just before the bag is opened.

Continuity: When Shawn and Gus find Johnny G's body in the car, he's slumped forward in the shots inside the car but slumped back in the shots seen through the windshield.
