Three Coaches & a Bobby - S3-E12
Continuity mistake: The two women near Peggy, who are sitting on the benches in the stands, are seated on the fourth and fifth levels in the wideshots, but in the close-up they're seated on the third and fourth levels.
Revealing mistake: When all the vampires are saying "for the dark", and one gets staked, there's a mark on his shirt where the stake's about to come through before it actually happens. Plus Buffy's hands are in the wrong place for her to have pushed that stake through, as well as there being no stake in her hand when the vampire gets dusted. Not only that, but the mark isn't even close to the vampire's heart to begin with. (00:34:50)
Make Love, Not Warcraft - S10-E8
Continuity mistake: When Liane comes down after Eric says "Bathroom", you can see Cartman, and to the left, Stan. However, when the camera instantly changes to a side view, Stan is no longer there.
Continuity mistake: When the sarcophagus explodes, the blast door they escape through has no card reader. Once they stand up it's there. (00:37:55)
Other mistake: At lunch, when Sam is using a spoon to shape his mashed potatoes on the tray, his right arm clips through the tray just as he says, "Maybe I should clear out the east wall like this." Then, when Sam says, "Maybe I should fortify the south side first," he's using the spoon to move the mashed potatoes on top of the tray, but his arm and spoon are under the tray, so it looks as if the potatoes move on their own. Additionally, when Sam states that he's so confused, the spoon held up in his right hand appears to vanish in the next shot.
To Kill a Mocking Alan - S1-E5
Visible crew/equipment: When Alan drives away at the end shouting 'No way you big spastic. You're a mentalist.' the whole crew are reflected in the car windows. (00:27:10)
Visible crew/equipment: When Elliot first walks into Maya's office to find her in there with a crying Nina, a boom mic drops into view. (00:12:51)
Opera House Murder Case: File 2 - S1-E22
Other mistake: At the beginning of the episode, the characters are gathered thinking back about part 1 of the case. Amazingly enough, the propmaster's armpit ate the A of his shirt. Now he's not a "BADMAN", he's a "BADMN." (00:02:05)
Continuity mistake: During the first prisoner's trial at the Holo Court, a 790 Unit is operating the memory search machine to use as evidence against the criminal. He is shown standing next to it several times to operate the buttons, activate the switch, and control the memory video feed back. However, in one shot from the side view of the prisoner, the 790 Unit has vanished from next to the machine, but is back again moments later to hit the switch sending the prisoner on his way to his death.
