Character mistake: The 'perfect' German postcard Rollin has written is full of mistakes: 1) The 'sie' must have a capital 'S' because it's a personal pronoun; 2) The only sentence stops in the middle and makes no sense; 3) The word 'Besten' has to be written without a capital because it's not a noun; 4) In Germany the house number stands after the street name, not before; 5) The streetname makes no sense. Too many mistakes for a so-called 'perfect' card. (00:04:40)
Kid + Plane + Cable + Truck - S4-E3
Character mistake: Desi states that the stall speed of an F-16 is 250 knots. Not true. The F-16 stall speed in level flight is around 120 knots. (00:02:40)
Character mistake: Patterson - the oceanographer - at one point claims that Lithuania is land-locked. She should know better; in fact, Lithuania has a coastline of close to 100 km on the Baltic Sea.
The Hammer - S1-E10
Character mistake: Raylan Givens tells Judge Reardon that he carries a ".45 Glock" but this is untrue. Throughout the series with the exception of the beginning of the first episode Raylan Givens carries a Glock 17, which is only chambered in 9mm parabellum. His backup can be seen to be a Glock 26 which is also in 9mm.
Character mistake: In season 4 episode 13, "Tuesday," when Marshall is meeting with Ulrich, he is both able to understand and reply in German. In season 5 episode 15, "No Hard Feelings," Marshall almost misses the opportunity to change the street light from red to green, because the text is all in German. Jack has to tell Marshall which word is green, indicating that Marshall does not understand the German language.
The Joker's Flying Saucer - S3-E24
Character mistake: Vertigris tells Joker he planted a bomb in the Batmobile while it was parked in front of City Hall/Police HQ. Only in this instance, it wasn't. It was parked in the alley out back, the better to hide his bomb-planting from public view, so it's strange that he'd forget this. (00:08:15)
The King of the Delta Blues - S2-E6
Character mistake: "Are you going to send in the calvary?" is said twice. It should be "cavalry". (00:09:40)
Character mistake: When Cowley visits Bodie at the squat, the unwashed and dirty Bodie suggests Cowley should stand downwind of him. Downwind Cowley would smell Bodie; he should have said upwind.
When in Rome - S1-E3
Character mistake: Nobody in this scene knows how to dance the tango that is playing. (00:16:35)
The M.O.D.O.K. That Time Forgot! - S1-E2
Character mistake: M.O.D.O.K. refers to Hoobastank as "the Beatles of the late 90's." Hoobastank only released one album in the 90's, and they didn't become popular until after they released their second album in 2001.

Character mistake: Lance and May walk into a bar in Massachusetts. As they enter, the camera pans and shows a large banner on the front window. The banner is advertising "game day" food and drinks. In very large letters the banner shows Boston Red Socks. The actual correct spelling is Boston Red Sox. (00:05:45)
Character mistake: Zordon begins to explain to the Rangers about their powers and then their Zords. At one point, he says "You need only to turn to the power of your Dino Zords." However, the subtitles get it wrong and spell it as if he's saying "Dinosaurs" instead of Dino Zords which is what he says. (00:10:38)
Character mistake: After Ray Palmer says he's an Eagle Scout, he says to Leonard Snart, "be helpful to others, scout's motto." The Boy Scout's motto (including Eagle Scouts) is "Be Prepared." "To help others at all times" is part of the Scout's oath, but that's different than its motto and not something an Eagle Scout would mix up.
Suggested correction: It was a joke, that applied to the situation. Wasn't meant to be literal.
There is zero indication of any joke, implied or otherwise, especially since he could have correctly said "oath."
Character mistake: Despite being a Greek mythology buff Maxie Zeus says "Vulcan" when he meant "Hephaestus" the Greek god of fire and the forge when he first spoke with Batman.
The Short Day of Private Putnam - S2-E28
Character mistake: Hanley's call sign is Checkmate King Two. But his radio man recites, "Checkmate King Two, this is White Rook." Should have been the other way round.
Route 7-11 - S1-E12
Character mistake: In this episode, they constantly refer to the semi as an eighteen wheeler. The tractor would have tandem (two) rear axles with dual tires. This one has only one rear axle on the tractor. Added up, the rig only has fourteen wheels.
Character mistake: The title card says "Plummers Academy" instead of "Plumbers Academy."
Six Forgotten Warriors Chapter 4: The Six Fight Again - S5-E5
Character mistake: When the Red Skull reemerges from the vortex, he sees Chameleon and acknowledges him as his stepson. However, only moments before this, Kragov explicitly stated that the Chameleon was more like an adopted son to the Red Skull.
