Corrected 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.
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.
Correction: Since the murder was revealed as a hoax at the end of the episode, the scissors were probably fake as well.
Corrected 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.
Correction: After multiple viewings, I think his eyebrows go under his glasses, but just give the illusion of his eyebrows going over his glasses.
Corrected 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.
Correction: Bart has been 10 since the first episode. Since the Simpsons don't age, every birthday of Bart's is his 10th birthday. Homer is the only one that seems to age.
Corrected entry: The Simpsons don't only have one car. Why doesn't Homer drive the red station wagon that appears in almost every episode, instead of using a scooter?
Correction: This is a question, not a mistake. Perhaps Marge was using it or it could have been in the shop. Or maybe Homer was simply too stupid to realize another car was available to him.
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.
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.
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.
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 the bus goes past Ned Flanders while he is performing a drink-driving test with Chief Wiggum, you can see heads floating in mid-air.
Correction: I've just checked this scene, and none of the heads appear to be floating. You can't see below a lot of them, but they're not floating.
Corrected entry: Even though Maude Flanders is dead, she is seen at Vance Connor's award ceremony. (Try and find Ned and you will see Maude).
Correction: You can only see them from the back, and from that, all we can deduce is that she looks a little like Maude. It could actually be any random person.
Corrected entry: Homer runs outside to see the college students packing. He asks a couple why they are leaving. The couple is putting a statue of a head on their car. The statue blinks the same time the male college student does.
Correction: That's not a statue head, that's a person. In the zoom out right before Homer starts talking to them, you can see his torso in the car windshield wearing a green shirt and he has his arm on top of the car. When Homer starts talking to the couple, the man looks like a disembodied head on top of the car.
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.
Corrected entry: During all of the flashbacks, Homer is in stage 1 hair loss (birth of Bart), but shouldn't he have the amount of hair he had after finding out about Lisa's birth? If the flashbacks did occur 8 years ago, shouldn't Marge be pregnant and Homer be bald?
Correction: Marge has already had Lisa by the time of the flashbacks - Lisa as a baby is seen in one of them.
Corrected entry: When Rev Lovejoy talks to Marge about how Flanders kept bothering him, like visiting the church and phoning him, in one of the scenes Lovejoy and his wife are sitting in a cafe in France, and Flanders manages to phone him. Thing is, how did Flanders know where they were, or even know they were at that cafe?
Correction: That is the joke. Flanders is so persistant in his confessions and questions that he'll find Lovejoy no matter what.
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.
