Special Edna (a.k.a. Love and Marking) - S14-E7
Deliberate mistake: When Bart and Edna are watching "Holes" in the IMAX theater, Edna sighs and pulls out a locket which we can see the back of. After opening it up to reveal pictures of her and Seymour, we find out its actually a triptych when she opens up another image of Seymour's mother. From the way she unfolds this extra picture, Seymour's mother would have had to be facing outwards, but in the previous shot the back of the locket was blank.
Continuity mistake: At the birthday party Maggie is playing in the sandbox with one of Apu's kids. She and Apu's son both have pink with green polka-dots party hats on. After she is taken out of the sandbox by Moe, Homer takes her and she keeps squirming out of his arms. Look on her head and you'll see that her party hat has disappeared, and never comes back.
Scuse Me While I Miss the Sky - S14-E16
Continuity mistake: When Skinner opens the door to the room Lisa is in, there is a red book with white rings around it behind the door, it is easily the most noticeable book on the shelf. When the shot cuts back, the book is suddenly blue.
A Star is Born-Again - S14-E13
Audio problem: When Lenny talks about selling Sara's autograph on eBay, his lips don't match what he says.
Continuity mistake: When Grandpa goes nuts outside the house he knocks over 2 bins and spills rubbish on the pavement, in the next shot the bins and the rubbish are gone.
Brake My Wife, Please - S14-E20
Continuity mistake: Whilst Moe is talking to himself about going back to barber college the door to his bar is wide open. When the shot changes to him when he says "Who the hell am I talking to?" the door has suddenly closed. There was not enough time for it to close between shots.
Large Marge - S14-E4
Continuity mistake: After Homer paints "El Homo" on the wall, he paints over it so that none of the letters are visible. In the next shot a couple of the letters are visible, and are only struck out with one line.
The Great Louse Detective - S14-E6
Continuity mistake: Frank Grimes' gravestone appears to look different from "Homer's Enemy" and "Alone Again, Natura Diddly."
Large Marge - S14-E4
Continuity mistake: In some shots, the incorrectly-colored lobsters have their claws taped shut, and in others they don't. It's completely random.
Dude, Where's My Ranch? - S14-E18
Continuity mistake: Carla's "Carla" ring is only on her finger in the closeup.
Special Edna (a.k.a. Love and Marking) - S14-E7
Factual error: During the video screening at the Teacher of the Year committee, the panel is watching the teacher who acts like Robin Williams. In the video the main judge says "Next" and pushes a button on the video control. It goes to the video that Bart Simpson sent in. How was this possible? The video control would only fast forward the video and two separate entries would not be sent in on the same tape. The committee wouldn't have spliced the footage together onto the same tape as the tapes were piled up on the desk. At the start of the scene one of the judges mentions to put in the next tape.
Treehouse of Horror XIII - S14-E1
Audio problem: When Homer is playing the piano, and Marge is playing the cello, Frink grabs Homer and pulls him into the room. However the playing of the piano continues, even after Homer is pulled away. (00:13:50)
Dude, Where's My Ranch? - S14-E18
Plot hole: Lisa says Luke was her 1st crush. What about Nelson, Corey, Mr. Bergstrom, Thelonius and the boy that works at the library in 'Bart's Girlfriend'?
Suggested correction: She didn't have much of a crush on Mr Bergstrom, she mainly admired him because he was kind. However you are correct about the others.
Brake My Wife, Please - S14-E20
Continuity mistake: When Hibbert handcuffs Bart to the radiator, for one brief second, his cast and bandages disappear. They return in the next shot.
Continuity mistake: On the trip back from the gardens, Homer rear ends the car in front of him on the bridge which sends Maggie flying out of the car. In a long shot of the bridge whilst Maggie is in the air you can see the car has changed to an orange color instead of the usual light purple color. The two cars in front of them also change during shot. The one in front of the simpsons changes from a normal red mid sized car to a blue van, whilst the car in front of that one changes from being a green car to a blue one during the aerial shot of Maggie.
Continuity mistake: When Homer bangs on the screen in the testing booth, the little sign on the top left of the glass that was there earlier is no longer there.
Continuity mistake: When Homer goes to catch Maggie (after flying out of the car) he jumps over two cars in front of him and then falls over the second one and there is no sign of any cars in front of him. However in the shot before he climbs over the cars the aerial shot of Maggie flying in the air, all the cars on the bridge are bumper to bumper with no spaces in between them.
Dude, Where's My Ranch? - S14-E18
Audio problem: Homer groans and Mr Burns' lawyer points out that the note that he groans in is A flat. On the version that I heard it on (The Simpsons Christmas 2 DVD) he actually groans in the note A.
Audio problem: When Bart's gang is singing their song and Nelson is playing the banjo, he sings "because she's dead" and plays different notes yet his hands don't move along the neck of the guitar.
Dude, Where's My Ranch? - S14-E18
Continuity mistake: When Luke jumps off of the horse to save the rattlesnake egg, the horse changes from being beside Luke to beside Lisa between shots.
