The Sinner and the Sandman - S5-E2
Plot hole: Ian Avery-Cooper loses his lottery ticket which is immediately picked up and appropriated by Leonard Corbyn. However, Avery-Cooper immediately reports the loss to the shopkeeper who sold him the ticket. All lottery sales staff are trained in what to do under these circumstances, because it happens a lot - they cancel the lost ticket and issue a new one. Since Avery-Cooper used the same numbers every week this would not pose a problem, but even if he didn't the ticket would be recorded on the seller's computers and could be precisely reconstructed. This would be even easier since Avery-Cooper reports the loss within a minute of it happening and we see that he has the receipt for the sale in his hand. Corbyn's stolen ticket would be worthless and Avery-Cooper would be able to claim his rightful winnings. If nothing else Ian could have simply bought another ticket with the same numbers.
It's Not Easy Being Green - S5-E16
Factual error: Boomhauer's car, Ms. Sally, has a Texas flag license plate on it. These plates were not issued until 1992, but Ms. Sally was driven into the quarry in the late 70's or early 80's.
Continuity mistake: When Buffy is talking to Riley, she puts the scarf on her head, on his hand. He talks to her and says "Maybe I am the bad guy," and in the next frame her scarf is back on her head again, then off again in the next frame. (00:24:20)
Visible crew/equipment: When Alan views the kitchen, a boom mic shadow can be seen in the top left of the screen. (00:13:05)
Continuity mistake: In the introduction, when TJ pulls the ball off Gus, Gus is covered in gum. When they are walking into the school, the gum has disappeared.
Factual error: Kyle says he has to log on before school. The next shot shows "Monday 8 days later." 8 days before is a Sunday. (00:04:45)
Plot hole: Throughout the show it is reported several times that Billy and Ally met when they were both eight years old in a park by sniffing each other's bottoms. However, when Billy is buried in season 3 his tombstone reads, 1968-2000, making him 32 years old. Ally is only 29 and does not turn 30 until later in that season which would at the very least, put them 2 years apart. (00:41:15)
Continuity mistake: In the first episode of season 10, when Marissa is holding a dog while talking to Elaine, the way her arm lies around the dog's neck changes several times between shots.
Continuity mistake: Carter and Cadet Haley enter the Stargate and we see them through the "puddle." When they come out on The Other Side, their positions are reversed.
Clash of the Megazords - S1-E29
Other mistake: When TJ goes to get the Phantom Ranger's ruby, he is standing on top of the battery pack on the Turbo Megazord. There are no other places for him to stand. After he destroys and knocks off the battery pack, in the next shot he is still standing in the same place, but there is nothing for him to stand on.
Mr. Jealousy - S7-E2
Continuity mistake: When Jack and Finch are talking about Vikki barging into the office, Jack is not wearing a vest, but in the next shot he is, and when he stands up it is gone again.
Visible crew/equipment: When T.J. is playing basketball in the garage, before the helicopter scene, you can see the boom mic fly across the top of the screen for about 2 seconds.
Audio problem: Almost all the newsroom links in this episode were redubbed, and at times the overdub falls entirely out of sync. When Austin Tasseltine begins speaking one of his lines before Morris has finished, the latter's "Belt up, will you?" is an ad-libbed response to this mistiming.
The Ex-Files - S1-E5
Continuity mistake: When Dharma is visiting her uncle (a dentist) and she's in the dentist chair, she has a little spot of water on her bib, the shot moves, then it moves again and the spot isn't there anymore.
Continuity mistake: When Sheila Carlisle has hanged the dead head up on the wall of Eugene's office, they are all looking at it and the eyes are looking straight in to the room. Later in the episode, the eyes are looking more to the right.
Continuity mistake: After the Squirmese chef sets up his additional ingredients, Corky answers the video phone. During Corky's conversation, Al's kitchen can be seen with no trace of the chef or his ingredients.
The Bing That Wouldn't Leave / You Promised! - S1-E11
Continuity mistake: In "The Bing That Wouldn't Leave" Bing often changes size. Most of the time he's about half as tall as Norbert and Daggett but most notably near the end when he hugs Daggett he's about the same size as him.
Continuity mistake: In the Season 1 episode "Too Cute," Quinn mentions to Sandy that Sandy picked out Quinn's outfit that she's wearing. This could not be possible as Quinn had that outfit (the same one she always wears in every episode) since BEFORE they moved to their current town and before the girls met anyone in their school they first went to in the first episode.
Super Nova - S1-E2
Revealing mistake: When Stan, Xev and Kai are walking to the Memory Chamber, they seem to walk out of a two dimensional line at the lower left into the scene. The set and green screen weren't quite synched.
Continuity mistake: When King mentions the two brothers' "destiny", his big feline is at Young Diabolik's side, facing King and the others. Aerial shot, and the panther is at King's side facing Diabolik. (00:05:00)
