Like Father, Like Klown - S3-E6
Corrected entry: In Krusty's story, when he's doing his performance with balloons on the stage, we can see Krusty's father in the background, watching and clapping at Krusty. (00:09:10)
Tree House of Horror II: A Simpsons Halloween - S3-E7
Corrected entry: At the beginning of Part 1, we are told that the Simpsons are in Marrakech, Morocco. At the airport, however, we can see on the building 'Marrakesh Airport' - the spelling is different. (00:02:20 - 00:03:15)
Correction: Transliterations from other languages, especially unrelated languages, into English are inexact and even inconsistent. How many ways are there of spelling, in English, the name of the dictator of Libya? Gaddafi, Qaddafi, Kaddafi ...
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.
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)
Correction: 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.
Corrected entry: If Bart has been ditching karate class, wouldn't Akira contact Bart's parents about it? (00:09:15)
Correction: 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.
Mr. Lisa Goes to Washington - S3-E2
Corrected entry: Isn't it out of character for Nelson Muntz to be in an essay contest? (00:05:30)
Corrected entry: At the end of the episode Homer says, "To Flanders, the richest left-handed guy I know." The problem is, Flanders isn't; Mr.Burns is the richest left-handed guy he knows, because Homer told Mr.Burns to go to the store. (00:19:50 - 00:21:10)
Correction: Two ways to correct this: 1) Homer isn't exactly the brightest bulb in the box, as evidenced by the multitude of times he's forgotten the names of his loved ones (especially Maggie, poor baby), so the notion that he'd forget about Mr Burns (his boss, who he despises most of the time) isn't outside the realm of possibility. 2) Perhaps, in one of those rare moments of Homer-esque brilliance, he didn't mean "rich" in the monetary sense, but rather in the humanitarian sense.
Corrected entry: When Otto plays Bart's guitar for the first time on the bus, it generates an amazing electric sound, but it isn't even plugged into an amp.
Correction: That's the joke.
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.
Corrected entry: In the beginning of the episode, the family goes to the Googolplex theater but when the show cuts to a shot of the movie screen when Bart and Lisa are watching Space Mutants, the decor around the screen indicates that they are at the Aztec theater. (00:03:20)
Correction: Seeing how Springfield used the same plans for Springfield Elementary and North Springfield Elementary it should be no surprise that two theaters in Springfield have the same decor.
They could have been owned by the same company at one time or changed owners. This is also a running gag on the show such as what's on the other side of The Simpsons' house?
Lisa's Pony - S3-E8
Corrected entry: When Homer is on the phone with someone in his work station, (I think it's Lisa) he's talking on a phone that's connected to his work panel. When he turns to his right, there's another phone connected to the wall. Why would one person need two phones?
Correction: One closed-circuit intercom for calls made inside the plant, and one regular phone. For instance.
Tree House of Horror II: A Simpsons Halloween - S3-E7
Corrected entry: As Maggie makes her wish, the wall color in the room changes from pink to green. (00:03:50)
Correction: The only shot with a green background is that of the actual paw, and it's an overhead view showing a green floor. The wall colour never changes.
Corrected entry: When Selma is in the bath with a cigarette, she sinks under the water dragging the cigarette with her. However, if you look and listen very closely, the sound of the cigarette being extinguished happens very slightly before it actually makes contact with the water.
Correction: In the shot as she is just about to go under the water, you can see the cigarette start to glow a bit redder. This would mean Selma is inhaling as she is going under the water. As she would be inhaling, a small area below the lit area would start to get hotter and so would make sense that the sound of it being extinguished just a split second before the lit area goes under the water.
Tree House of Horror II: A Simpsons Halloween - S3-E7
Corrected entry: Mr. Burns and Smithers put Homer in the bag. They weren't carrying a bag when they got to the cemetery. (00:17:20 - 00:18:10)
Tree House of Horror II: A Simpsons Halloween - S3-E7
Corrected entry: At the end of Part 1, the crowd carrying Flanders jumps from being on his front lawn to the middle of the street. (00:08:30)
Correction: No they don't, they are on the pavement in every shot.
Tree House of Horror II: A Simpsons Halloween - S3-E7
Corrected entry: When the family (except Marge) starts eating candy, their costumes are suddenly off, when they never had time to take them off. (00:01:25 - 00:02:15)
Tree House of Horror II: A Simpsons Halloween - S3-E7
Corrected entry: When Homer shuts the door after his candy gets stolen, we only hear eggs being thrown at the door. In the next shot, the pumpkin beside the door appears to be broken. (00:01:20)
Correction: They presumably kicked it or stood on it which wouldn't necessarily be a loud enough noise for us to hear from inside.
Lisa's Pony - S3-E8
Corrected entry: Homer takes a drink of his beer, but his mouth doesn't open. (00:14:25)
Correction: His mouth may only be slightly open, and you don't need to fully open your mouth to drink. It is possible to drink with your mouth only slightly open.
Lisa's Pony - S3-E8
Corrected entry: The kitchen appears to be very different after Marge finds out Homer bought a horse. (00:12:10 - 00:13:00)
Correction: The kitchen does not at all look different.
Lisa's Pony - S3-E8
Corrected entry: When Lisa calls Homer at the power plant, the same footage of him sleeping and waking up in the beginning is used. (00:18:55)
Correction: There is nothing contradicting continuity by reusing this shot, so this isn't really a mistake.
Correction: His father didn't know that it was his son until the other Rabbi sprayed him with the seltzer, washing off Krusty's makeup.
