Tree House of Horror II: A Simpsons Halloween - S3-E7
Corrected entry: How can Moe not realize he got a prank call that's really long, and isn't even asking for a name? (00:11:35)
YoshiCorrected entry: When Bart first writes 'Treasure Island' on the board he has written it on two lines, the 'Treasure' is above the 'Island'. But after a couple of shots we see the blackboard again and the two words are next to each other.
domwhit23Correction: The word "Treasure" is written above "Island" in all shots of the blackboard.
Super Grover
Corrected entry: When Judge Harm snaps her flashlight in half it's still lit.
Correction: Her flashlight turns off as soon as she breaks it in half. It does not stay lit.
NikolaiCorrected entry: When Lisa mocks Bart in French, she sings, "Vous êtes Baby Stinkbreath." However, "Vous êtes" is the formal construction. A person would not use this when speaking to his or her brother, especially when deliberately being disrespectful towards him. "Tu es," the informal form, would be more appropriate
DavidK93Correction: Lisa may still be learning, and it's an easy mistake to make.
Correction: She's 8 years old. A child making mistakes is not uncommon.
Ssiscool She is shown to have superior intellect.
Even the smartest people make mistakes. Neil deGrasse Tyson said it wouldn't be possible for BB-8 in The Force Awakens to rove over sand and chalked it up to a visual effect, only for the filmmakers to prove to him that it was not a visual effect.
Phaneron Corrected entry: At recess, Bart splits his pants in front of the girls. This split isn't visible in any other part of the episode. (00:02:35)
YoshiCorrection: This episode takes place over multiple days so he could have changed his pants at the start of each day.
moviefan2345Corrected entry: In the scene where Homer is in the bathroom, Marge yells to Homer for breakfast. We see him running naked without a towel but by the time Homer, Bart, and Lisa get to the breakfast table, Homer is wearing his usual shirt and trousers.
Correction: We only see him running naked out of the bathroom, nothing else. So he ran in to their bedroom, got his clothes on, and ran downstairs. No mistake.
Andreas[DK]Half-Decent Proposal - S13-E10
Corrected entry: Artie says that he has been thinking about Marge for the last 20 years. However, we have seen in previous episodes that Marge got pregnant with Bart just out of high school, and he is 10. They can't have graduated more than 11 years ago.
Correction: Marge got pregnant with Bart in 1980 (See Episode: I Married Marge, Season 3). They married soon after this. This is to do with the slightly larger plot hole of everyone in the Simpsons always being the same age (at least they stopped aging after 1990 when the show started). This is a cartoon convention and not a mistake.
Correction: In the episode "that 90s show", Lisa discovers that Homer and Marge are nearly 40 and Bart is 10 so they must have had Bart when they were 30. Assuming they graduated high school at 18, that gives 10 years before having a child and the 10 years after which is 20 years, so Artie is correct.
The Good, the Sad and the Drugly - S20-E17
Corrected entry: When Willy is knocked out by the falling letters, there are 3 Ns that fall sideways next to his head, making it appear as if he was sleeping. There are only 2 Ns in "Springfield Elementary School."
Correction: If you look closer at the N nearest Willie's head, it is actually the "M" from "Elementary" with a piece missing.
Corrected entry: In the opening, Homer tosses out the uranium stuck on his shirt. It bounces once, and disappears mid bounce.
Movie NutCorrected entry: For season 1, in the introduction Lisa narrowly misses Homer on her bike, then lets it roll into the garage. If you look closely, you can see the bike disappear before the screen moves.
Correction: The bike doesn't disappear - it rolls to the left hand side of the garage out of sight.
Ssiscool Holidays of Future Passed - S23-E9
Corrected entry: When Carl and Lenny are talking about the brain switching ceremony in Moe's Bar they speak with each others voices. For this to happen they would have to have switched vocal chords too.
Correction: This is speculation at best, not a mistake, since there's never been a brain switch to prove this. Plus, the vocal chord is controlled by muscles to change speech, and the muscles are controlled by the brain. This is why people can impersonate other people's voice (or at least change their own voice).
Bishop73Corrected entry: On the family tombstones, Maude's tombstone reads 'Mod Flanders'.
Correction: The tombstones say "Maude, Rod, Todd, and Ned". It doesn't say Mod on any tombstones.
AAL117Corrected entry: When Lisa is researching artist Johan Oldenveldt, it says he was born 6 May, 1942 and died 38 years earlier on 5 December, 1904. (00:06:50)
Correction: The article she looks at shows his lifespan as 6 May 1859 - 5 December 1932.
Margical History Tour - S15-E11
Corrected entry: In this episode, King Henry VIII executed five of his six wives. In real life, Henry only executed two, Anne Boleyn (his second wife)and Katherine Howard (his fifth wife).
Margical History Tour - S15-E11
Corrected entry: Jane Seymour is shown being beheaded. She actually died a couple weeks after giving birth to her son, Edward, from complications arising from the birth. (00:06:00)
jleCorrected entry: Homer's pet lobster, "Pinchy" is red. However, lobsters aren't red until you cook them. When they are alive they are brownish/black.
Correction: Pinchy is a darkish, almost brown color, and only bright red when cooked (of course the Simpsons also depict people as being yellow).
Bishop73Corrected entry: Lisa is singing "One (Is the Loneliest Number)" and looks up the composer to find out that he "died of a heart attack suffered on Valentine's Day." Although Harry Nilsson DID suffer a massive heart attack on 14 Feb 1993, he didn't die of heart disease until 15 Jan 1994.
Captain Defenestrator Correction: Lisa's search said 'Harry Nilsson - Died of massive heart attack SUFFERED on Valentine's Day'. The operative word here is 'suffered'; so what that means is Nilsson died (eventually) of a heart attack that began on the 14th of February the year before. It's tricky semantics, yes but it's correct. It would've been a mistake if he'd said 'died of massive heart attack on Valentine's Day'.
Corrected entry: When Homer and Marge find Mrs. Bellamy's body, the body is shown to be neatly placed on the ground with Bellamy lying on her back. Homer then lifts up the body and it is shown that there is a pair of scissors stuck in her back. If scissors were stabbed in her back, then this means it wouldn't be possible for the body to be neatly placed on the floor lying on her back, as the scissors would cause the body to push upwards. (00:09:50)
Casual PersonCorrection: Since the murder was revealed as a hoax at the end of the episode, the scissors were probably fake as well.
zendaddy621Corrected entry: In the shot of Smithers, right after Moe says "Your queen is back", Smithers' eyebrows overlap his glasses, and you can see the outline of his glasses on his eyebrows.
NikolaiCorrection: After multiple viewings, I think his eyebrows go under his glasses, but just give the illusion of his eyebrows going over his glasses.
NikolaiCorrected entry: In the beginning of the episode, Bart is talking about being 10 years old even though his 10th birthday is in the episode "Radio Bart" later in the season.
sam145
Correction: He does know that it's a prank call and that Bart is the one calling. He goes along with it because he doesn't want to make Bart mad.
I'm pretty sure that this is just an internet theory.
No, in this episode Bart has supernatural powers and the whole town lives in fear of him. He's making people do what he wants because he can.
