Visible crew/equipment: When Gibbs and Ziva are in the "safehouse" Ziva set up for Ari, a crew member and his boom microphone are seen on the left of the screen, right before Gibbs climbs the ladder to remove the hidden camera spying on them. (00:30:10)
Kobol's Last Gleaming (2) - S1-E15
Visible crew/equipment: In the scene where Starbuck attempts to retrieve Apollo's arrow, a crewman in a red tee shirt and dark vest can be seen standing just behind and to the right of the display case as she is shooting out the glass.
Clash!! Sonic VS Knuckles - S1-E5
Revealing mistake: Right at the end of the episode, when Amy is telling Knuckles he should apologize, Amy has two right hands.
Continuity mistake: When Anakin prepares for take-off, C-3PO and R2 can be seen standing right by his fighter. But as he takes off, they can suddenly be seen standing by Padmé - several floors above.
Plot hole: Throughout the series, auxiliary characters are always far too willing to give all kinds of information to Tru. Doctors and registrars constantly give her privileged information about patients and students. Tru is often able to retrieve information like addresses and phone numbers from people's service and utility companies, when normally you must verify your own information before they will even talk to you about your account. Of course there can't be an episode if Tru doesn't quickly find the person who asked for her help, even though she doesn't usually know much more than their name, but it's still a bit conspicuous.
Continuity mistake: When Raven telekinetically reassembles the broken chime bead necklace, it has about nine beads and is rather tight, but before and after that the necklaces feature about 13 or 14 beads and are wide enough to fit around the others' necks.
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: 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"
Worlds Collide: Part 3 - S3-E6
Plot hole: In their previous encounters with the Triceratons, the Turtles had to learn the hard way that the Triceratons breathe not oxygen but a combination of nitrogen and sulfur, which is detrimental to most Earth lifeforms, and thus had to wear special rebreathers. When the Turtles, Splinter, April and Casey enter Zanramon's throne room along with Traximus, none of them wear any breathing equipment to protect themselves from the hostile atmosphere.
Other mistake: The voice-over mentions a DC10 almost hitting an Airbus. The plane shown has two engines - a DC10 has 3 engines.
Beauty and the Obese: Part 1 - S1-E1
Audio problem: After the bartender himself offers a lap dance to the man who just talked to Persephone, the man walks off to the right of the screen. The bartender offers him a cheaper price when the camera cuts to a different angle after he walked away. At this point, the man would now be just off the left side of the screen, but when you hear him say "No" it comes from the right side when listening with headphones. (00:02:42)
Plot hole: Tori somehow knows who Marah and Kapri are, despite never meeting them before.
