The List/Haunted Train - S1-E8
Corrected entry: When Arnold sets his alarm clock, it says 5:45 (a little early for bed), but when he puts it on his desk, it's 10:30.
Benchwarmer / Cool Jerk - S1-E11
Corrected entry: The players are listed by first name on the scoreboard, and their numbers aren't listed, so there's no way of telling which player is which.
Correction: It's pretty well implied in this show that everybody knows who everybody is. So having only names is perfectly ok.
Downtown as Fruits / Eugene's Bike - S1-E1
Corrected entry: When Arnold is fixing Eugene's bike, he's not wearing his hat.
Correction: Unless we saw him without his hat a second before this isn't a mistake, even if it's rare for Arnold to not be wearing his hat.
Downtown as Fruits / Eugene's Bike - S1-E1
Corrected entry: In the teeter-totter scene, Gerald's shirt is number 3 instead of 33.
Correction: This scene took place years before, at what looks like day care. So it would be a different shirt than the one he has now and could easily have a different number on it.
Das Subway / Wheezin' Ed - S1-E12
Corrected entry: The sun is well above the horizon when they leave the theater, but it sets less than 30 seconds later.
Correction: If you look you can see the sun going down when we first see it when they step out of the theater. This is a cartoon so it's perfectly ok to suspend reality for awhile.
Tutoring Torvald / Gerald Comes Over - S1-E13
Corrected entry: In Gerald Comes Over, Gerald says whenever he goes to Arnold's house he always goes straight to Arnold's room and has never seen all of Arnold's house. Also he seems never to have met any one else that lives there, but in previous episodes we have seen him in other parts of Arnold's house and met many of the people that live there.
Correction: Other than the few episodes that take place at a certain time; this series is not meant to be taken in chronological order. Just roughly during the same 4th grade school year.
Corrected entry: At the end of the first training scene (when Arnold first tries to catch the fly), one of Arnold's feet has no toes; also, just before Arnold falls down the chimney, he has three arms.
Correction: No he doesn't have three arms. You are either mistaking his foot when it pops up for a third arm or your mistaking his two arms for three when we see his arms move quickly and the cartoonist make it look a little like he has more than two arms to show his falling like they often do in cartoons.
Downtown as Fruits / Eugene's Bike - S1-E1
Corrected entry: At the beginning, Iggy can be seen very briefly without his sunglasses.
Correction: What exactly is the trivia here? We simply see Iggy lift up his sunglasses for a short moment; there is nothing substantial about it. And it's not even the only time he is without them; in "Arnold Betrays Iggy," he is not wearing them at all, both at the beginning and the end of the episode.
Correction: 5:45 was the time he was setting to wake up, not the actual time. When we see it on the desk we see the actual time.
