Visible crew/equipment: In the episode where Nicole throws bleach onto the pool table, the scenes before they go out on the town take place inside the household. The camera spends time moving through the house and you can see a cameraman (with a camera) standing in the background and quickly move away. While the camera is moving through the house looking at the floor it passes over a box of equipment and a boom mike.
Factual error: When they first assault the city, the Greeks construct catapults. Only problem: catapults were invented at 400 - 300 BC, i.e. about 800 years later; and the first models looked similar to giant crossbows. The one-armed onager and similar types (as seen here) were a later Roman invention.
Continuity mistake: When Kimiko says "Will you two please stop abusing the English language!", Raimundo's eyes are blue.
Continuity mistake: When talking in the pub, Sarah's hands are around her wine glass or not, depending on the shot.
Continuity mistake: Colonel Gathers says to Brock Samson, "You're not in the Marines anymore." But in the earlier episode, "Past Tense," after the credits, there is a flashback to college again and Brock says, "I'm off to join the Army"
Continuity mistake: Episode 1-22, Kansas v. Tom's Parents. In the opening sequence where Tom and Susan is attending a party, watch the glasses and their contents. In some shots Tom is holding one glass in his left hand, in other shots he's holding it in his right. In another shot he's holding two glasses. The number of olives in the glasses also changes between shots.
Continuity mistake: At the beginning of the show, when the boys are eating eggs and sausages, Alicia gives Jimmy a sausage. In the next shot, the sausage is in another position, and in the shot after that there are two sausages on his plate.
Continuity mistake: "Ikke i Rute": During Roar's flashback the cigrarette his brother is holding disappears.
Continuity mistake: When they first enter the Y'Lyntian city and are attacked by the Lava Wraiths, Raphael gets his sai melted by them. But after taking their goodbyes from Versallia, Raphael has his sai stuck back in his belt.
Continuity mistake: Jamie and Adam are shooting at Police badges to see which one would potentially stop a bullet. When they get to the third badge, it is held up to the camera. It says 'Jamie Hyneman' on the badge. The badge is then shot, and shown again to the camera. This time the engraved writing on the badge has changed to 'Adam Savage'.
Continuity mistake: When Malene Bork is standing over Michael's bed in the start of the episode, you can't see that she is pregnant. But later when she is talking to Sara, suddenly it looks like she is in the 7th month of her pregnancy.
Continuity mistake: At the beginning, Kate's friend gives her ex-fiance's letter to Kate. The letter is held differently in consecutive shots.
Revealing mistake: In brother Justin's padded cell, the far wall is obviously a painted backdrop. It even flutters when the orderly and doctor walk in! The only solid part is a couple of feet at the end, that Justin leans up against.
Plot hole: Tori somehow knows who Marah and Kapri are, despite never meeting them before.
Factual error: The crash took place in 1987. When we hear about the American salvage company that was hired to find the wreckage, we see a scene of traffic in Washington, DC that has a model of Lincoln Town Car that was not produced until 1998.
Episode #1.2 - S1-E2
Continuity mistake: When they are playing The Battle of the Sexes, Matt is shown wearing his penalty clothes in one shot before his turn comes up. His clothes are normal in the next shot, and after that is when he loses on his turn and puts on the penalty clothes.
Beauty and the Obese: Part 1 - S1-E1
Continuity mistake: Right after the opening scene where the model suddenly inflates to fat, we are taken to The Tender Loins club where the exterior shot shows a line of people with a bouncer checking each one. In this shot, his arms are down at his side, but then it cuts a close up and suddenly he has his hand lifted to his face looking at someone's I.D. (00:01:40)
Continuity mistake: When Adam gets angry at Joan in the art room because of the camera, his half-made sculpture is sitting on the desk. When he grabs his bag toward the end of the scene, he accidentally knocks it over, unbalancing it. But in the next shot it's balanced again, then suddenly it's unbalanced. This happens several times between shots, and can even be seen in one shot before he knocks it over.
