Adios, Señor Magistrado - S1-E26
Character mistake: During the tavern meeting, Sergeant Garcia calls Magistrado Carlos Galindo "Comandante."
Character mistake: After Anakin says to use the walkers (AT-TEs) as boarding vessels, Rex calls the first one an AT-AT (a vehicle that does not even exist at this point in-universe) while ordering a battalion of clones into it. (00:04:10)
The Hairy Scare of the Devil Bear - S1-E8
Character mistake: Velma says bears only have four claws. Wrong, they really do have five claws.
Character mistake: Bret fires at "John Wesley Hardin" four times, but the doctor and all the witnesses say there were three shots.
Character mistake: Troy calls for the "Twistornado" but his card reads "Windrive"; the cards have always read exactly what the rangers called for.
Character mistake: When the office receives a code red alert, there is a close-up shot of the alarm, where there are two clocks next to it. One of the clocks represents New York time. The other represents London time. The clock representing New York reads the time as 10:40 and the clock representing London reads the time as 4:40. The time difference between New York and London is 5 hours, not 6 (occasionally 4 due to DST). (00:03:40)
Suggested correction: London is five hours ahead of New York normally, but Episode 5 takes place on April 25, 1946, so it is reasonable to assume Episode 1 takes place not long before that. England went on British Summer Time on April 14, 1946, while New York didn't go on Daylight Savings Time until April 28, 1946, so from April 14 to April 28, 1946, London was 6 hours ahead of New York, so the clocks would be correct.
Proof Through the Night - S1-E4
Character mistake: Dominic said the MIGs were coming in 015° but the readout says 105°. If they were at heading from 015, the triangles representing them would be in the upper right quadrant of the radar circle, close to the zero.
Smoking Gun - S1-E2
Character mistake: When the bad guys put the generator in front of the air vent, Nigel looks at the white smoke and pointing at it says "Carbon monoxide." Carbon monoxide is colorless, white smoke is mostly condensed vapor. (00:35:20)
Character mistake: When the woman is looking at the high school photo of She-Hulk at the high school reunion, she says "Oh, look. Remember her? Jennifer something or other." You can see that her full name is written directly underneath the photo, so there's no reason why the woman would look at the photo and not know what Jennifer's last name is.
Character mistake: Dr Smith who has some of The Robot (ie, bravery and courage) quotes The Fall of The Light Brigade but mistakenly says "into the valley death rode the five hundred" when it is actually 600. Both Dr Smith and the Robot would know this very famous poem's most well known line. (00:44:45)
Suggested correction: There's nothing to suggest they would know the poem exactly, especially since you yourself don't even know the actual name of the poem. It's "The Charge of the Light Brigade."
7 Continents for 7 Koopas - S1-E22
Character mistake: When King Koopa notices the Koopalings running to him, the screen with Antarctica has its title misspelt as "Antartica." Also, the dragon that appears on the screen for Asia goes from green-yellow to white and blue.
Champion vs. Creator, Part II - S1-E27
Character mistake: Pegasus says his toon world cannot be penetrated, but that is not true since it's a magic card, so any card that destroys magic cards can destroy it. Furthermore, monster special effects can also destroy it.
Character mistake: Whilst brutalising Pinder, Egrorian asks if he can feel his humerus grinding against his radius, but the bones in the forearm are the radius & ulna. The humerus is the single bone from the shoulder to the elbow.
Character mistake: In s01e08, "Q and A", Yelena moves her bishop to B6. The announcer says that's going to win it (the game gets interrupted at this point). However, that move does not put the computer (her opponent) into checkmate, it doesn't even put it into check. Her bishop is on a dark square and the computer's king is on a white square.
To Walk with the Serpent - S2-E14
Character mistake: Westerbrook deliberately burns his own right hand in the ceremonial flame. But at the end of the episode, he says, "I gave my left hand for the cause."
Character mistake: No referee in wrestling would allow a double team to occur without either trying to break it up or counting to five. Yet here he allows The Golden Girls to do so twice.
Character mistake: Shaun says that the underground facility is "built like a bunker", but the single missile they dodged just created a huge hole a moment earlier. (00:11:40)
Armageddon Now: Part 1 - S4-E13
Character mistake: Callisto's sword is missing. When she appears in the Xena Season Three finale "Sacrifice", her sword has reappeared. It is never explained why Callisto doesn't have her sword during her three appearances on Hercules the Legendary Journeys.
Yomigaere! Eiyuu Densetsu - S1-E1
Character mistake: Not to dispute physics in an anime about people drawing arcane cosmic powers from constellations, but when Marin explains to Seiya what happens when you shatter a rock into smaller pebbles, she says that you "destroy its atoms." That's not how physics works and luckily for her, Seiya and everyone else in Greece at the time, she did not create a nuclear fission in the palm of her hand just to prove her point.
Character mistake: Jessie's dance moves don't match what the other girls are performing, even though it's a choreographed routine.
