The Simpsons (1989) - 1325 mistakes in entire show

Other: When Bart flashes Lisa's laser at Principle Skinner's bottom, Chief Wiggum can still see it even when his car is in the way.

Continuity: This is a mistake for the introduction for the later episodes. When Homer screams, he turns round. You see this in a wide shot. There are no boxes to the right of the door in the garage. However, two just appear out of thin air when he runs through the garage.

Continuity: When Homer's Vegas wife shows him the video in front of Marge, it shows Homer kissing Ned. This didn't happen when she showed it in the Vegas episode.

Continuity: Lewis changes from black to yellow when Milhouse dares Bart to pull Santa's beard off.

Continuity: When Bart leaves the school, you can see that his skateboard is green and perfectly flat. But when he is skating through the crowd and past the people at the bus stop, the skateboard has an orange stripe down the middle and is raised at the rear.

Deliberate "mistake": After Homer brings Santa's Little Helper home, Homer and Marge hug, and if you look behind them, the background is upside down. There is a picture hanging upside down, and there is a lamp which seems to be hanging from the ceiling. Then in the next shot, the background is normal.

Continuity: While having breakfast, all of the Simpsons' glasses of orange juice keep disappearing and reappearing throughout the scene.

Continuity: For seasons 1 and 2, in the introduction Lisa narrowly misses Homer on her bike, then lets it roll into the garage. If you look closely, you can see the bike disappear before the screen moves.

Continuity: In series 17, episode 2, at the end of the episode where Homer is on the field talking to Buck the baseball player, the stadium is crowded. When Homer and Marge are leaving in their baseball golf car one second later, the stadium is empty.

Continuity: In the episode "Bonfire of the Manatees" the scene where Marge is in the car upset at Homer, the door to their house changes from open to closed then open again between shots.

Audio problem: After the donut delivery guy asks Carl why all the donuts are piling up, Carl responds with Lenny's voice.

Continuity: When Maggie goes through the checkout at the beginning, Marge's trolley is grey and has a red handle. But in the next shot, when Maggie pops out of the bag, the trolley has no red handle, and is a turquoise colour.

Continuity: Bart yanks Homer's beard off in the mall, Homer then takes Bart into Santa's workshop. When they are inside Santa's workshop, Homer's beard is back on, despite the fact that he didn't put it back on, he let it fall to the ground when Bart pulled it off.

Continuity: When Homer walks out Circus of Values with his purchases, he bumps into Flanders, and all the presents scatter everywhere. Watch out for a red present with a green bow that goes flying near the left hand side of the screen. As soon as it hits the ground it turns into a pink box with a white bow wrapped around it, with no shot changes.

Continuity: In the introduction for all episodes, initially Maggie's seat is light purple. However, in the wider shot of her and Marge, the seat changes to a burgundy colour.

Continuity: When you see a shot of the church from outside in the scene where the bee sharps sing there, look closely at the sign. You can see that it says 'Also: The Bee Sharps', only they don't name themselves that until later on in that episode.

Other: When Marge is speaking on the phone to her sisters, her sisters say something that sounds like they said that Homer is ugly. Marge then puts down the phone wire that she was curling round her finger. It is easier to see this when you are using DVD, because then you can go into slow-motion, but you can temporarily see that the phone wire disappears when Marge puts it down. It is at the very end of an early scene, because as soon as this happens it changes to another scene.

Continuity: In the bit where they sit on the sofa at the start of each episode, there is one rather long one where it starts off with the Simpsons dancing in a line, then gradually evolves into a circus with elephants and men dancing around fire. Look closely in between Homer's right leg and the dancing woman on his right. There is a pile of books on the little shelf underneath the lamp and telephone, and just as the camera starts zooming out from the line of dancing, the orange book on the left noticeably changes to purple.

Factual error: (Episode 17-1) Alec Baldwin, as an expert on manatees, says that they are also called dugongs. Manatees are found in Atlantic coastal waters and in the Amazon and tributaries. The dugong is a distinct species found in the coastal waters of the Indian and southwest Pacific oceans.

Other: During the theme, the Simpsons' mailbox flag is on the wrong side of the mailbox. (Flags are always on a mailbox's right side, when viewed from the front. The one at the Simpson home is on the left side of their mailbox.).
