The Spanish Inquisition - S2-E2
Revealing mistake: At the very end when The Spanish Inquisition bursts into the courtroom, you can see that Biggles is not played by Terry Jones (as he is playing the accused judge in the court sketch).
Factual error: A character in the episode has invented denim, but denim was invented in 1873 and was being used widely up to the time period of the series, which is set in 1893.
Factual error: Wanda's father opens his briefcase of DVDs and one of them is Malcolm in the Middle. But the bomb that killed him fell in 1999, and Malcolm in the Middle didn't start airing until 2000.
Continuity mistake: When Kelly is putting the number card on Logan, you can see one on Kendall behind him, when he shouldn't have had one yet.
My Sister, the Homemaker - S5-E12
Visible crew/equipment: At the beginning of the episode, Jeannie is talking on the phone by the stairs and her sister is hiding behind the banister. Her sister stands up for a moment and shows her full face, revealing that it is actually Barbara Eden's stand-in wearing the green costume.
Revealing mistake: In the episode where Denise tries on her wedding dress Jim leaves the room to go and wash up. As he opens the door to leave the living room if you look down towards the front door you can see Dave stood by the door frame waiting for the next scene.
Factual error: In the mall where Jimmy meets Irene there is the Pandora logo in the background when Jimmy is going up the escalator. Pandora didn't open its first store in New Mexico until 2013. (00:27:00 - 00:28:00)
Revealing mistake: When Brad wears the sunglasses and holds the pole, you can easily see the string that holding it up.
The Burning - S9-E16
Continuity mistake: At the beginning of the episode, when Puddy is farewelling Elaine on the street, he is standing on the sidewalk and leaning through the driver's window. The following shot when she pulls out quickly, you can see through the windows of the car that Puddy is nowhere to be seen.
Gourmet Night (a.k.a. Gourmet's Paradise) - S1-E5
Revealing mistake: When the Colonel first meets Basil, the same shot is used twice of the Colonel twitching.
The Long Legs of the Law - S2-E1
Revealing mistake: At the very beginning of the episode, Leonard Pearce is waiting for the cue for his character to start looking for his teeth. He's standing in the living room, between his room and Del and Rodney's room. (00:00:25)
Continuity mistake: Sue says that she "matured" aka got her period, on Sept 21, but in the episode "Forced Family Fun", when they go camping and she gets it, they go before school starts, which is well before the end of September.
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)
Revealing mistake: There are numerous times throughout the series where the supposed big city of Metropolis is actually just a back lot set and none of the buildings are more than a couple of storeys high. Quite often the green hills of Southern California can be seen beyond the set and between the buildings.
Factual error: At the beginning of the intro, the narrator says that the only way to resurrect a vampire is with a sacred rite that can only be performed once a century when the moon is in the eighth house of Aquarius. In Astrology, the eighth house is Scorpio.
Continuity mistake: Chase gives Zoey a radio in this episode, but in 1-3 Webcam, when Zoey, Quinn and Nicole are in Zoey's room trying to figure out who is telling the girls' secrets to people, you can see that radio above Zoey's head.
Audio problem: When Michael is forced to do "errands" for Brennen, they stop by Jonathan Carver's house to get numbers from him for a voice key. The code played back at the facility is 71348. He says "3" in a medium pitch (tone) at the house, but it is high pitched when played back at the facility; he says "8" in a medium pitch, and it's also high pitched later. And finally he says "9" in a low pitch and it's played back medium pitch. Also very obvious is the fact that Jonathan never says "1" or "7."
You Gotta Lose This Job - S3-E7
Visible crew/equipment: When 'Hannah' and Lilly walk into Rob Reiner's office, the multiple head studio lights are reflected on Hannah's large black sunglasses.
Continuity mistake: Scooby finds a clump of ape hair stuck in the wine cask. It cuts to the gang, then back to the cask as they walk up and suddenly the clump of hair is twice as thick. (00:16:45)
Shrink It Up - S2-E1
Continuity mistake: When Rocky is saying things that she has been pushed into doing, she mentions the time they danced on the wings of a plane. However they didn't do that until a few episodes later.
Suggested correction: The entire series was set in an alternate history of sorts, so most, if not all, historical "inaccuracies" cannot be regarded as mistakes.
