The Simpsons (1989)

The Fat and the Furriest - S15-E5

Continuity mistake: When Homer realises that the bear was only agressive because of the electrical tag, they share a bear hug. The back of Homer's shirt is torn to tatters, and his back is bleeding. Immediately thereafter, the back of Homer's shirt is completely intact.

Treehouse Of Horror XVI - S17-E4

Continuity mistake: At the end of "B.I.: Bartificial Intelligence," Homer climbs onto the ceiling and turns his head in a parody of "The Exorcist." He then lets go and lands on the bed. The only problem is that his body landing doesn't match the position it would from what we see on the ceiling. If he dropped down his face should be face down, body facing up and his head would be closer to the end of the bed. When he lands, his head is near the pillows, his body facing down and his head facing up.

Lummie

Homer Badman - S6-E9

Revealing mistake: In the scene where Marge's coat pocket bursts open, the candy flows onto the floor. However if you look to the right of her some of the candy seems to almost float above the floor. The candy's direction is completely to the right but because of the floor being angled it spreads over one woman who is standing and there is nothing there to support the candy. (00:04:30)

Lummie

Homer's Barbershop Quartet - S5-E1

Audio problem: In the scene where the Be Sharps first sing "Coney Island Babe" (I don't know what the song's really called) at Moe's, Skinner sings the rhythm. But when they sing the last few lines, you can still hear Skinner's part, but his mouth is moving like the rest of the group.

Treehouse of Horror XV - S16-E1

Continuity mistake: When Ned saves Moleman, we see where Ned is standing, there is no manhole beneath him yet when he catches Moleman there is one there. (00:02:30)

The President Wore Pearls - S15-E3

Continuity mistake: At the end of the episode Lisa gets on the school bus and in the back of the bus there is an emergency door with a small window in it. The following shot she starts singing out the back of the bus but the window has disappeared.

Lummie

Homer's Triple Bypass - S4-E11

Continuity mistake: When Homer is eating the bacon and what looks like scrambled eggs after claiming Marge's oatmeal had a bug on it, the close up of the bacon shows that it is pink/purple and the eggs are yellow but the in the following shot, when Bart says, "Dad, there's a bug on that." the bacon and the eggs switch colours.

Lisa's Wedding - S6-E19

Continuity mistake: When we first see union flag on fire, the flames are already consuming over the half of its upper edge. Then when we see it reflected in Hugh's eyes, no more than a half of the edge is burning.

Treehouse of Horror XIV - S15-E1

Continuity mistake: After Homer tries to stab himself with the banana, he drops it. But when Nelson's clothes disappear, the banana has vanished.

Goo Goo Gai Pan - S16-E12

Continuity mistake: In the first shot of Selma on the hospital bed, there's nothing behind Patty. However, when Marge starts to speak, we suddenly see two bags of drip mounted on a dripstand behind her. (00:01:55)

Hamster

Marge Gets a Job - S4-E7

Continuity mistake: When Bart comes back into the classroom after the wolf attack, Ms Krabappel is writing on the black board and there is quite a bit of writing up there. After we see Bart the shot goes back to Ms Krabappel and all the writing has gone.

Lummie

Moe Baby Blues - S14-E22

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.

Lummie

Colonel Homer - S3-E20

Continuity mistake: When Homer and Marge are entering the cinema, Marge is taking Maggie with her. But when watching the film, Maggie is nowhere to be seen.

Marge Gets a Job - S4-E7

Continuity mistake: Mr. Burns gives Marge a present when she starts her new job. The present is light purple with a red ribbon around it. Seconds later though, the present turns to orange with a red ribbon around it. (00:11:45)

Hamster

New Kid on the Block - S4-E8

Continuity mistake: You may have to look carefully for this mistake. When Marge picks up the 'Das Butt' video, you can see the cover. In the next shot, you can see Marge holding it so you can't see the cover. But when she hands it over to Ruth, she twists the video round and you can see that nothing is visible. You may have to see it a couple of times.

Sideshow Bob's Last Gleaming - S7-E9

Character mistake: Homer drinks 6 non-alcohol Duff at the air show, but is charged for 8.

Sweet Seymour Skinner's Baadasssss Song - S5-E19

Continuity mistake: In the air duct, the dog comes up behind Willie in a straight line and licks his feet, we saw what the duct looked like when Willie turned around. However, when the children start throwing stuff at the duct, from the outside there is a sharp bend right behind where Willie and the dog are that wasn't there in the internal shots.

Milhouse Doesn't Live Here Anymore - S15-E12

Continuity mistake: Milhouse is holding the Monopoly set in the Simpsons house. Then when his Dad comes in he isn't. Granted he could have put it down, but it isn't anywhere we can see, so he would have had to put it down behind the sofa which is somewhat unlikely.

Marge in Chains - S4-E21

Continuity mistake: When the bottle of bourbon is found and taken out of Marge's pocket, the bottle is grey. But when Sanjay throws it to Apu, and Apu catches it, the bottle has now changed to a brown colour. (00:08:30)

Hamster

Lisa the Vegetarian - S7-E5

Continuity mistake: Homer opens the door on Bart just before he shows the kids his BBQ invites but there is never a door there in the Simpsons' home, only a doorway.
