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)
The Itchy & Scratchy & Poochie Show - S8-E14
Corrected entry: When Itchy shoots the apple through the arrow at Scratchy's head, it punctures a vat of carbolic acid which spills onto Scratchy, turning him into a skeleton. Carbolic acid, or phenol, is poisonous but not corrosive.
Correction: An Itchy and Scratchy cartoon is entrely exempt from having to follow the rules of reality. OR, you could argue that since within the Simpson's universe the writers of Itchy & Scratchy have always been shown to be pompous and unimaginative college boys that don't do their research.
Correction: Bear in mind that this is the episode in which nerds are mocked for nitpicking cartoons.
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).
Lisa on Ice - S6-E8
Corrected entry: When Lisa runs into Bart's room and throws a snowball at him, it is quite a powerful throw and on target as it hits him in the face. Yet when the kids are receiving academic alerts in the gymnasium, Lisa can barely throw the piece of paper she has been given. Surely she wouldn't have been able to throw the snowball so well if she lacked such skills?
Correction: Not exactly. Once, I threw a tennis ball hard enough to give a kid a good black eye pretty dang fast. However, when my brother was trying to teach me baseball about a day later, with a similar tennis ball, I couldn't throw it nearly as fast.
Also, Lisa probably felt more confident about throwing the snowball at home compared to doing it at school.
Corrected entry: The Narrator of this episode, in describing The Simpsons, says "THIS NORTHERN KENTUCKY FAMILY." This is the only time that they have ever TOLD viewers where they live. It is at the very end of the episode while they are sitting on the hillside.
Correction: This is actually talking to the Simpson family as ACTORS, not as the characters they play. The family in "real" life may be from Northern Kentucky, but the characters they portray could be from anywhere.
Correction: It's been dismissed as a fake. They don't actually live in Northern Kentucky (they could, but we have no concrete evidence). To add to the mystery, the subtitles say Southern Missourian family.
Tree House of Horror II: A Simpsons Halloween - S3-E7
Corrected entry: When Homer buys the severed hand, the person selling it says "I strongly advise you not to purchase this item". Then why is he even selling it in the first place if he'd advise people not to buy it?
Correction: He may only want certain people (such as those he does not like) to buy it. He's advising Homer not to buy it as he's done no wrong in the seller's books.
Dude, Where's My Ranch? - S14-E18
Corrected entry: When Lisa tells Marge about Luke for the first time, Marge says 'I didn't marry the first boy I - Well I did. But you shouldn't." Wrong. Before she had a crush on Homer, she loved Artie Ziff from high school. She didn't marry him, however. Everybody blatantly knows that Marge married Homer, her second crush.
Correction: Homer was her first love. She never admitted to loving or having a crush on Artie Ziff. Marge went to the ball with Artie in spite of Homer and what he did to her but she never loved Artie and never admitted to loving him. Also in the statement she makes she never admits to anything. Its presumptious she was going to say the first boy she had a crush on. It could have been the first boy she had a real relationship with.
Marge vs. the Monorail - S4-E12
Corrected entry: When Lurleen is talking to Kent Brockman, her voice is completely different than how we heard it in "Colonel Homer".
Correction: This is intentional. The hoarse, scratchy voice (along with "I spent last night in a ditch") is supposed to denote how rough her life's been since "Colonel Homer".
Corrected entry: When Mr Burns asks Larry about his life, he mentions that he stayed at the orphanage until he was 18, and then got the job at the stall. He also mentions the small detail of seeing a blimp. Yet at the end of the episode, he says he has a wife and kids. Wouldn't he have mentioned them earlier to Mr Burns, if he included such a petty detail as a blimp?
Correction: See, that's the entire joke: to Larry, the appearance of a blimp was more interesting than his wife and kids. The reveal at the end of the ep (that he has this family) is funny for precisely that reason - that he's ignored them entirely all this time, with no concern. Just because you don't get a joke doesn't mean it's a mistake.
Corrected entry: Homer says Marge is the only woman he ever kissed. But he kissed Mindy Simmons earlier in the series.
Mr. Lisa Goes to Washington - S3-E2
Corrected entry: Isn't it out of character for Nelson Muntz to be in an essay contest? (00:05:30)
Corrected entry: At the start when Homer leaves with Bart, Patty and Selma have their hands in their laps. As soon as they start speaking however their arms are crossed in front of their chests. (00:01:50)
I, (Annoyed Grunt)-bot - S15-E9
Corrected entry: Why did Lisa call her new cat Snowball V? There wasn't a Snowball IV, and Lisa kept Coltrane's name the same.
Correction: The cat may be named this because it is the 5th cat. If it was called Snowball IV, then Lisa may have forgotten about Coltrane.
Corrected entry: When Homer goes to another bar we hear him say "Ah, my new watering hole." His mouth doesn't move. (00:17:10)
Corrected entry: When Homer goes to the barbecue, he grabs a plate of burgers. There isn't a burger at the top of the pile. However, when Flanders talks to him there is a burger on the top.
Corrected 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.
Correction: The word "Treasure" is written above "Island" in all shots of the blackboard.
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)
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.
Who Shot Mr. Burns? (2) - S7-E1
Corrected entry: When Smithers realises that he shot Jasper, instead of Mr. Burns, he mentions that he left the meeting early in order to watch Pardon My Zinger. However, in the previous episode, you see him walk out of the meeting with everyone else, very slowly. (00:06:25)
Correction: True, however, everyone stopped walking after exiting the meeting and Smithers continued to walk, so he did leave before anyone else did. He said he left the meeting early probably because he was delirious and couldn't remember it correctly.
Who Shot Mr. Burns? (2) - S7-E1
Corrected entry: Burns' sunblocker was meant to always block out the sun above Springfield. Yet when the Townspeople go to rip the sunblocker down, it is perfect daylight. (00:03:30)
Correction: They weren't actually in Springfield when they ripped it down. The Sunblocker was obviously out of town as shown where the scene where they go to rip it down starts.
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.
