Correction: We see Bart clear a number of things from the table and then the angle changes to one where we can no longer see what's on it, so no mistake.
Corrected entry: The hamster gets electrocuted mildly by a food pellet with an electric current. However, it is an electrical insulator so it couldn't have an electric current.
Correction: It's impossible to tell what the battery is connected to. Yes it's the same shape as a food pellet but hamsters will gnaw on anything including the bars of their cages, which are metal.
Corrected entry: When the two pictures are shown of the tyre fire, now and 25 years ago, the clouds in the sky are the same.
Correction: Not a mistake but a joke by the show's makers. Even 25 years, long after the fire should have gone out yet it is still raging and everything including the clouds are exactly the same.
Corrected entry: Somebody with glasses and a hat drowns in a river, but later when everybody is looking for the treasure, he is there as if nothing has happened to him at all.
Correction: The man who goes in the river is driving his car and it goes under the water but we never see him drown. As soon as he goes under the water the shot shows Bart. The guy could have simply got out of the river and ran to the treasure site after that. He was in a convertible car and there was enough time from the car sinking to seeing him at the treasure site to have covered that distance.
Correction: There may have been more than one item of this doll and the one he showed Homer was for display purposes. The fact that there was a phone number to call for problems with the doll makes it very possible this wasn't just a one off doll. Even if there hadn't been more than one, he may have packaged it up before Homer left the store.
Corrected entry: Both the Australian boy's father and Marge say that the call cost $900. However America and Australia have their own dollars and hence different currencies. Because of the exchange rates, surely one of the values would have been different.
Correction: At the time they are told about what they owe they are being notified the amount is $900 AUSTRALIAN dollars. Because of exchange rates changing every day, the currency difference will only be made an issue when the amount is actually bought. The Simpsons as well weren't likely going to be able to afford the expensive call so I don't think how much it would be in US dollars was going to be much of a concern.
Corrected entry: Before the Simpsons are in their house talking about the Itchy and Scratchy Movie, there's a line of people waiting to see it that extends past their house and down numerous streets. When it shows one of the kids talking, the window behind them shows that all the people have vanished.
Correction: There is time, while Homer is in shot, for the line to have moved forward.
Corrected entry: When Aunt Gladys Bouvier dies, she leaves her pet iguana to her sister, Jacqueline Bouvier (Marge's Mom.) If she never married as she claims, Jacqueline's maiden name would have been Bouvier, not her married name. This would also mean that Patty, Selma and Marge would not be Bouviers either.
Correction: It is customary for the wife to take the husband's last name, not mandatory. You can even switch back after a divorce or a death.
Correction: The boy by Lisa has black hair, whilst the one in the next shot has purple hair. Hence they are two different boys.
Correction: Most times the tusks are removed for circus performing elephants. They don't want to have a trainer impaled on the tusks. Also, Female Asian elephants usually lack visible tusks, as do males in some populations.
Corrected entry: Neither Barney nor Homer underwent any sort of physical or medical examination at all. Homer has a heart condition, he has had bypass surgery, and yet he is still allowed to take part in the mission. Also, both of them are surely too overweight to be allowed to participate.
Correction: The whole mission wasn't well thought out to begin. At the end of the day they were looking for a "Blue collared slob" to attract fans, and in that case Barney and Homer were perfect. The fact they were overweight and in average health was not NASA's main concern. Also they do undergo examinations but we probably don't see all of them. One scene we see them doing a lung capacity test.
Corrected entry: At the start of the episode, the Simpsons celebrate finally paying off their first mortgage. But earlier in "The Computer Wore Menace Shoes", the credit card machine said that Homer was on his fifth mortgage.
Correction: True. They still have four more mortgages to pay.
Corrected entry: Moe says there hasn't been a woman in the bar since 1979, implying that the bar has been around for at least a couple decades. But in a later episode, a flashback shows that Moe's grand opening was nine months before Bart was born. And we all know Bart is 10.
Correction: Bart was also ten in 1989, when the show first premiered. If you go off that, the dates work out.
Corrected entry: When Lisa tells Marge about Luke for the first time, Marge says 'I didn't marry the first boy I - Well I did. But you shouldn't." Wrong. Before she had a crush on Homer, she loved Artie Ziff from high school. She didn't marry him, however. Everybody blatantly knows that Marge married Homer, her second crush.
Correction: Homer was her first love. She never admitted to loving or having a crush on Artie Ziff. Marge went to the ball with Artie in spite of Homer and what he did to her but she never loved Artie and never admitted to loving him. Also in the statement she makes she never admits to anything. Its presumptious she was going to say the first boy she had a crush on. It could have been the first boy she had a real relationship with.
Corrected entry: When we see a flashback of Mr Burns' ancestor in 1909, he looks at atoms from someone's pocket. Actually, atoms are smaller than microscopic so it would have been impossible for him to see the atoms through a magnifying glass.
Correction: That is what is technically known as the joke... Or, to be more specific, it is obvious that the elder Burns have no idea what he is talking about, or for that matter what nuclear science is about (seeing how he has men trying to split atoms with sledgehammers). Then, when he discovers crumbs or regular pocket lint in the employee's pocket, he believes that this is the miraculous "atoms" he has heard about and assumes that this working-class lowlife has been stealing from him. Ridiculous, as everybody who knows the first things about atomic science knows, but that's what is funny in the scene.
Correction: We can't see the bodies that the arms belong to becuase of the people standing in front of them, so we don't know whether there are bodies there or not.
