Corrected entry: Even though Grandpa Simpson is younger in this episode, a picture of his older self is hanging in the Simpsons' home. Creepy.
Corrected entry: John is wearing Homer's old bowling shirt which he got at the Goodwill, but at the end of the bowling episode, Mr. Burn's attack hounds tears Homer's "Pin Pals" shirt to shreds. How could John get that shirt at the Goodwill if the hounds tore it up?
Springfield Connection - S6-E23
Corrected entry: In the scene where Marge is chopping celery, the knife is always in front of the celery as she chops, and never passes through the stick of celery - so no slices should be cut.
pinkwaferLike Father, Like Klown - S3-E6
Corrected entry: Krusty's fancy coat is missing during dinner. (00:06:00)
YoshiCorrection: There was a few minutes between these two scenes and it would have taken only a few seconds for Krusty to take it off.
Corrected entry: Throughout the whole show, Homer indicates he has three religions. The first one where he becomes an astronaut, he says he is Christian. Then when he becomes a body guard for the mayor, he indicates he is Muslim when his instructor says he can't worship Muhammad and Homer replies, "Not even during Ramadan?" which is a holy day in Islam. And finally in "Bye, Bye Nerdy" he tells Apu he is Hindu.
Correction: The Simpsons are Christians. The Ramadan thing was just a throwaway joke. I don't know about the Hindu comment, but I bet it was a throwaway joke, too.
Corrected entry: When the meltdown is in progress Smithers says that Homer was hired under Project Bootstrap, yet in the episode titled "I Married Marge" we see that it was Mr.Burns himself that hired Homer.
Corrected entry: If the cops are standing right beside the room where Skinner's trapped, and the door is partially open, why would the cops NOT hear Skinner when he yelled? (00:19:45)
YoshiCorrection: This is a mistake, but it is the point of the joke. The cops tear apart Skinners room to find him, but don't hear him yelling in the next room.
Corrected entry: How can Lisa eat breakfast and get on the bus in a matter of seconds? Also, Bart changes from being in his pyjamas to his normal clothing in no time at all. (00:01:30 - 00:02:15)
YoshiCorrection: If lisa can eat breakfast and bart instantly changes there could have been a small break between the two parts.
Corrected entry: Bart asks Lisa how she knows so much about the Talmud. She credits her imaginary Jewish friend. But Bart was with Lisa in episode 3-6: "Like Father, Like Clown," when she made an extensive study of ancient Jewish texts. So Bart shouldn't need to ask the question in the first place, and Lisa's answer is incorrect, or at least incomplete.
DavidK93Like Father, Like Klown - S3-E6
Corrected entry: When Krusty leaves, we can see Lisa at the door with Bart and Marge. However, she was sleeping just a few shots earlier. (00:10:20 - 00:11:25)
YoshiCorrection: Marge could have woken her up to see off their guest.
Corrected entry: When the school bus stops at Springfield Elementary, it is visible that the bus stops on the sidewalk. (00:02:20)
YoshiCorrection: Otto is driving. It is not impossible or a mistake for them to be parked on the sidewalk.
Team Homer - S7-E12
Corrected entry: When Bart's class goes nuts after seeing his "Down with Homework" t-shirt, we see Ralph sitting on the floor, eating paste. The problem is, Ralph is in Lisa's class, not Bart's.
Correction: If he's dumb enough to be eating paste he's dumb enough to be in the wrong classroom.
Corrected entry: The location of Evergreen Terrace and the Simpson home changes dramatically. In 'Homer the Great' the power plant car park runs past the Simpson's backyard while in the rest of the series its in the middle of a housing estate. In 'two bad neighbours' and other episodes there is a row of houses opposite the Simpsons, while in some episodes the Simpson's house is visible without opposite houses.
Correction: Whenever something like this happens it's usually done intentionally for comedic effect, such as Homer having to park so far away from work that it's right by his house. It's not like the writers and animators forgot what is around the Simpson's house.
Corrected entry: In some episodes where they show Marge as a teenager, she has long hair thats down and straight. In others, she has her hair the way it is currently, straight up.
Tree House of Horror II: A Simpsons Halloween - S3-E7
Corrected entry: When Mr. Burns is deliberately making Homer unconscious, he is exceptionally strong. He is supposed to be weak, as in "Homer Defined," when he couldn't give a thumbs-up. (00:18:00)
YoshiCorrection: Since this is a spin-off type episode it doesn't have to follow the other episodes. The Halloween episodes have completely random continuity, with people dying/being changed to other forms/attacked by aliens, etc.
A Tale of Two Springfields - S12-E2
Corrected entry: The people left New Springfield because of no food, but when Homer is punching the windows he get hotdogs from the store.
Correction: Actually, they left New Springfield because the roads were blocked off by the barrier, and there was no way to get more food into The Town. Also, when Homer was trying to convince them to stay, he said, "There's plenty of food for today." So there was still some food in The Town, like the hotdogs.
Kathy TjarksBurns Verkaufen der Kraftwerk - S3-E11
Corrected entry: After Homer loses his job, he is jamming a fork in the toaster. We see sparks coming out of it, proving it's plugged in, so Homer should have been electrocuted as soon as he did this. (00:15:20)
YoshiCorrection: Electricity takes the shortest route possible, in this case, between the toaster heating elements, through the fork, to some part of the toaster that is grounded. Homer is not grounded, there is no reason for the electricity to go through him. I am not telling you to try it, but you may be surprised.
Sol ParkerCorrected entry: If Bart has been ditching karate class, wouldn't Akira contact Bart's parents about it? (00:09:15)
YoshiCorrection: No. He didn't really sign up for anything and Akira never found out his name, he just turned up with his ten dollars and joined in, not like anyone got to know him.
Corrected entry: When Homer is dumping the treadmill off in the water, he sees Marge and the group of kids and runs off leaving the station wagon behind. In the next scene the station wagon is at home parked in the driveway.
Tobin OReillyCorrection: He could have easily gone back to get the car. There was a significant amount of time between the two scenes.
My Mother the Carjacker - S15-E2
Corrected entry: When Grandma Simpson is about to sign the first spot in the guestbook, the camera shows that the guestbook already has writings in it.
Correction: Those are just the lines to write your name on and such.
Correction: That's a picture of HIS father. In several episodes of The Simpsons it is established that Homer will look just like Abe as he gets older, and so on down the generations.
