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: Bear in mind that this is the episode in which nerds are mocked for nitpicking cartoons.
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)
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.
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: 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 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: 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)
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.
Corrected 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.
Correction: 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.
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.
Margical History Tour - S15-E11
Corrected entry: Salieri wasn't Mozart's brother - let alone his sister. Wouldn't Martin have been better as the jealous rival? (00:14:25)
Corrected entry: In the scene where Belle (the owner of the burlesque house) tells Homer about Bart breaking a valuable statue, Belle calls it a gargoyle, however this is wrong. A gargoyle has water shooting out of its mouth, the statue Belle was talking about, is called a grotesque.
Correction: While technically correct, the term 'grotesque' is now practically unknown to the general public, who refer to all such statues as gargoyles. Only an expert in the field would realistically refer to them as a grotesque and Belle, as the owner of a burlesque house, is unlikely to qualify for that status.
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)
Correction: This episode takes place over multiple days so he could have changed his pants at the start of each day.
Corrected entry: Nelson Mutz is one of the person banned for life by the comic book seller. If so, why he is seen later during Tom Savini's presentation?
Correction: He could have either snuck in or bribed/tricked the comic book guy.
CBG spots people in disguise and is stubborn in regards to people being banned.
Corrected entry: When Homer check the bills, he finds out Bart called Burkina Faso. He was trying to call countries in the Southern Hempisphere, when Burkina Faso is actually in the Northern Hemisphere.
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.
Raging Abe Simpson and His Grumbling Grandson in 'The Curse of the Flying Hellfish' - S7-E22
Corrected entry: When Bart and Grampa are on the shore looking at the paintings that they have just rescued from the bottom of the sea, the authorities suddenly show up. How did they know that they would be there, and that they would have the paintings?
Correction: The authorities mention they had been tracking the paintings for quite some time. Being the location of the paintings had been hidden even from those who stole it (Grandpa Simpson & Mr Burns had to get the keys to find it), the authorities would have likely tracked them until they did recover the paintings. If the pair had been tipped off they likely would have not tried to recover the paintings and the authorities might never find them.
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.
