Continuity mistake: When Margie Manners is shown mopping the Cleaver's kitchen floor she is using a sponge mop. When Wally comes in, the scene then shows Margie pushing a string mop against Wally's shoes.
Continuity mistake: Once Billy Numerous splits into 10 copies, you see the Titans standing outside the T-Car. The boys are on the ground and the girls, Raven and Star, are hovering above them. It then cuts to a camera move going around the car and suddenly Raven and Star are hovering above the car itself. (00:09:45)
Continuity mistake: When Jay is talking with his brother and finds out about his brother's cancer, he is holding a glass of scotch with a tiny bit of ice. When his brother approaches him the glass now just has ice with no scotch. We don't see the glass for a short period before he is about to sit in his chair and spills the contents of the glass, which now has the scotch and ice again.
Burning Down the House - S9-E19
Visible crew/equipment: During the scene where Mimi has moved into the warehouse, Drew makes a comment about the TV having surround sound - as the camera pans over him you can see a crew member in the background adjusting a light.
Visible crew/equipment: When Dianne's daughters have locked themselves alone in the room, just as Jerry is about to put the keys in the door to unlock it so they can prevent the girls from cutting their hair, the boom microphone dips into view in the room where the girls are alone. This boom mic is not from the "documentary" crew. (00:13:25)
Other mistake: Right at the start, as they're crashing, the computer narrates their rapidly-dropping altitude in feet. But the "altitude" dial we're shown is in metres. Most noticeable as they cross the 3,000 mark, when the computer voice and the height say/show the same number at the same time, despite the different units. 3,000m would be more like 9,000 feet, or 3,000 feet would be more like 1,000m. (00:03:20)
Where the Wild Kings Are - S1-E5
Visible crew/equipment: When the twins are tied up in Pupaley's cave, just as they get on their knees and beg to be let go, the hand of a crew member holding the end of the rope is visible at the right of the screen. (00:19:25)
Continuity mistake: When Adrian stamps "denied" onto Boyle's insurance claim form, there's blank spots where there wasn't enough ink on the stamp (which would happen because he had the stamp in his pocket for a while). But then when he says "denied" and holds up the form, "denied" is all filled in fully. Also, the red border is lighter and the location has shifted down.
Continuity mistake: In the final scene, John Ross decides to drink some of the whiskey from the bottle that his father, J.R. Ewing, left for him. The bottle of whiskey is about half full, filled to just about the bottom of J.R. Ewing's signature on the bottle. As John Ross reaches for the bottle, it is now suddenly only about 1/6 full compared to the half full it was from the previous shot. The level continues to move up and down. (00:41:45)
Continuity mistake: When Mary offers Walter the fast food bag of chicken soup, her hand disappears and reappears on the top of the bag. (00:34:40)
Visible crew/equipment: As Sal is leaving the apartment after Laverne breaks up with him, the backstage is visible through the open door during one shot. (00:21:25)
Continuity mistake: After Mike's mother tells him that she heard a prowler, when it cuts to Mike and Carl showing up at her house we see that the window is wide open, but when they move in closer ordering the "sicko" to come out of the hedge, the window is closed as it should be, until Mike's mother opens it when she sees that the "pervert" is actually Kay. (00:00:55)
Duck/Aren't You Chupacabra to See Me? - S4-E9
Continuity mistake: Mandy is in the library working on her report. When she's working on the second page, the writing is scribble, and on top of a stack of paper. A second later, the page says "CORN by Mandy", and the stack of paper is gone.
Visible crew/equipment: When Jadzia and Melora are in the runabout talking about relationships, Jadzia mentions having to go back 150 years for a Starfleet relationship; when it cuts to Melora the boom mic can be seen coming in through the front window. (00:23:05)
Revealing mistake: At the river to cross over to Mt Weather, the vine used to swing across the river is just a standard rope, camouflaged. You can see it best when Finn recovers it after Jasper has jumped.
Visible crew/equipment: After Hutch finds the ticking box with the clown and Starsky's badge inside, when it cuts to Hutch and Dobey walking toward the squad room, the cameraman and camera are reflected on the door's glass window. (00:17:20)
Continuity mistake: Aunt Clara crashes into the pagoda and is helped up by Darrin and Samantha. They head inside and you can see Aunt Clara's purse sitting in the pagoda to the bottom left. But when all three enter the house, Aunt Clara is now carrying her purse. (01:14:00 - 01:20:00)
The Night of Miguelito's Revenge - S4-E12
Revealing mistake: At the beginning of the episode, as Jim West walks away from the newsstand vendor and closes the magazine, a 1967 ad for DieHard batteries ("The DieHard Fights the Common Cold") can be seen on the right-hand page of the prop magazine, in a modern sans serif font.
Not in the Line of Fire - S3-E15
Continuity mistake: When the vendor throws the hotdog at the press conference, a lot of the toppings/condiments trail behind it. When the shot changes and the hotdog hits Mike, there are no condiments trailing behind it. (00:19:10)
Roger Codger - S1-E6
Continuity mistake: In the Area 51 flashback, the "RESTRICTED" sign on the lab door goes from red to blue between shots. (00:11:00)
