Continuity mistake: Benson visits Stabler at his home to confronts him about the FBI detail he has ordered to protect her. They talk outside and then Benson is seen walking away. The next shot shows a side shot of Benson approaching him again in silence but mouthing words to him. (00:49:00)
Visible crew/equipment: When Angel is fighting the demon, you can see an obvious camera and two hands in the bottom right corner. (00:27:10)
Jellyfishing / Plankton! - S1-E3
Continuity mistake: In Plankton! When Plankton pulls out a radio player to play his evil music on SpongeBobs pillow, it has disappeared when Spongebob wakes up. SpongeBob didn't move on it.
Factual error: The Lockheed 1011 was only produced until 1984. There's no way that in 1999 Toby would be flying on one that "just came off the line 20 months ago."
Plot hole: They're in the Clam complaining that they can't drink when they make the revelation that Brian can because he's technically 56. But Quagmire should be able to drink, as in a much earlier episode, he's revealed to be over 60.
Suggested correction: Quagmire considers the rest of them to be his best friends. He isn't drinking because they can't drink. He is complaining because since his friends can't drink - he won't drink, so he is still pissed.
It's still a plot hole considering Quagmire's age. I think the writers messed up big time.
Family Ties - S1-E22
Visible crew/equipment: After Rygel's transport pod returns to Moya, as the docking bay door slides open, in the shot facing everyone while they have their weapons drawn we can see the bare floor. However, when Aeryn checks Crais for hidden weapons and then as D'Argo approaches him, there's a blue crash mat on the floor. Then it vanishes again.
Continuity mistake: Tony's hair length alternates between a short buzz cut and longer in different shots in the scene where Sil, Paulie and Chris visit him after his mother dies.
Continuity mistake: Did any one else notice that Sheridan gave birth without ever taking off her pants?
Heads Of Beef / Klub Katz - S1-E11
Factual error: In "Klub Katz" the captian yells "Iceburg, Iceburg, on the starboard side." But when you see the iceburg and the ship, the iceburg was about to hit the bow of the ship.
Continuity mistake: Just after Sydney gets the book snatched from her by the guy in car, her hands stay near her body and don't move, but in the next shot her hands are thrown out to the side to add a surprised effect.
Plot hole: In the episode "10,000 Steps," the parents from Amy's case say they adopted their first son Daniel when he was 3 because they thought they couldn't have biological children. Howeve,r the birth of their other son Seth proved that theory wrong. But Daniel is 13 and Seth is 12, so when Daniel was 3, Seth would have been 2 already.
How The Elephant Got Its Trunk - S3-E6
Revealing mistake: The white around Papa's lips and eyes is slightly running when he is sprayed with water. however the white is supposed to be part of his real skin.
Happy Birthday, Kevin (or Happy Birthday, Douchebag) - S1-E12
Continuity mistake: After Carlos sees the snake on the pole he leaps off the roof onto the pole. When he jumps you can see it's quite a distance from the roof. After catching the snake he is holding onto the pole and asks to be helped back onto the roof. The other characters just put their hands out and pull him up. There was no way with the distance between the pole and the roof they could have come close to reaching him the way they did.
Revealing mistake: At the end it is not Helen against the filing cabinet - the face is different. Obviously a body double.
Character mistake: Tai says "And it started to snow in the middle of July" but later you find out that it takes place on August first.
Continuity mistake: The 4 Space Rangers (Carlos, TJ, Cassie, Ashley) morph on the overhanging gangway, then jump off to the ground below. We see them hit the ground, and in the very next shot, they're right next to the Galaxy Rangers, and Andross, who are on the other side of the courtyard. There wasn't enough time for them to move that distance.
Plot hole: At the end of the episode when Tommy has change the witches into little statues, he's a werewolf. Then he runs to Stacey and changes back. However, in Hello Nasty it takes a Haiku from Merton to change Tommy back.
Factual error: When Mike is describing his attempted invasion of Paris to the TA officers, he mentions going on Space Mountain at Disneyland Paris. However, Mike says that it happened in 1994, which must be correct, as the officers in an important interview like this would pick him up on the inaccuracy. Space Mountain did not open until 1995.
