Corrected entry: When Marge asks Homer to open the door for her sisters, he says "Patty. THELMA." (The English captioning has that mistake as well, but is correct in the Spanish captioning) (00:03:30)
Corrected entry: When Homer does the test again, he doesn't read the questions in order if you look carefully on the sheet. (00:18:00)
YoshiCorrection: There is no reason why he has to read them in order. He's answering the ones he knows first which is something many people do.
tw_stuartCorrected entry: Before the time trials start, we can see how far the track is, but while Bart, Nelson and Martin are racing, considering the speed they're traveling, the track seems much longer. (00:12:25 - 00:14:35)
YoshiCorrection: I've watched this scene again and there's nothing unusual about the length of the track or the time they take to complete it. When we see the track at the start we can't see the finish line so we have no way of telling if they take unusually long.
tw_stuartCorrected entry: If you watch the scene in slow motion where Nelson is attacking Bart at the time trials, you can see another Bart in the audience. (00:14:00)
YoshiCorrection: During this scene all the characters watching the race are blurred to give the impression of speed so there's no way to know if it's Bart since we can barely make out the faces. It's certainly someone wearing a red t-shirt but that doesn't make it Bart especially since the person appears to be much taller than a small boy.
tw_stuartCorrected entry: When Bart is showing his Soap Box racer To Martin and his other friends, we see an oil spill on the driveway which is grey. In another shot, the oil is black.
Correction: The view of the oil spill is from completely different angles so it's just a trick of the light. Oil can also be rainbow coloured in the right light.
tw_stuartCorrected entry: As Bart tells his friends about his racer, there is a set of stairs visible at an impossible area of the garage. (00:09:00)
YoshiCorrection: The stairs are inside the house, we are seeing the underside of them.
tw_stuartCorrected entry: On his soapbox derby racer, Bart is pounding his hammer on an area that doesn't have nails in it. (00:08:00)
YoshiCorrection: Pure speculation, we can't see the area he is hitting in enough detail to know if there are nails or not.
tw_stuartCorrected entry: During the finals, if there was a paper speedometer on the Honor Roller, why would the speedometer be working at all then? (00:20:10)
YoshiCorrection: This is a simple one, we never see the speedometer working. We see the needle fixed in one position before it peels off so no mistake.
tw_stuartCorrected entry: Homer complains that he missed a part of Joe Theisman. It's a TAPE. He can just watch it over again. (00:07:10)
YoshiCorrection: True but this is Homer, he could easily have forgotten or may just be irritated at the interuption. Either way it's not a mistake.
tw_stuartCorrected entry: Why would the audience NOT notice that Nelson was given a knife by his friends? (00:13:40)
YoshiCorrection: Even if they did see, why would they care? Knives aren't illegal and for all they knew, the knife could have been his to begin with.
Correction: He actually says Selma, and the DVD English subtitles (in Region 2 at least) also say this. Listen closely.
