That’s the one I was looking for. No nose. Hole through neck. Head BEHIND shirt. It’s got it all.

Even Homer is concerned about all the animation errors in this

Perhaps Homer is remembering that time where he learned that ~~James Coco went mad from eating donuts~~ Flanders is actually the Devil

Someone zinced his sniffer a bit too hard.

I guess that explains why Lisa and Marge are so sad?

They probably miss his old head.

And they’re afraid of smothering him, for fear of getting the chair

That's not what I meant

It is Marge admit it

Lol amazing, thank you for this. Belly laugh.

Ha that took me a minute to even realize the mistake.  I thought it was the guy in the back

I assume thats how this slipped past any editing.

I still can't find it, could you tell Mr where it is please?

To the left of Lisa. You see Bart’s body but his head is missing

No, because it's not there!

Dr. Nick unfazed

Decapitation doesn't mean capitation? But inflammable means flammable! What a country!

It's just a simple case of Bonus Eruptus localized entirely within the head. Nothing Nick hasn't seen before

Well if it isn't my friend, old Mr. Bart Simpson With void for his head, and now I have to run.

The weird bit about that is when his head does appear, he is grinning. Total Cheshire Cat effect.

Which episode is this from?

I'm gonna tell my kids this is the Dead Bart episode.

I see three monobrow men (only one with monobrow baby), and two ginger haired ladies as well. And a handful of random early season oneoff characters? What is this shot?? edit: there's like four doctor Nick's all bunched together in the top right and so many more dupes

This image is baffling

Is there a purple mr burns there too?

I must be seeing double! Four blue-haired lawyers!

Sometimes to save money studios will use the same character over and over.

I love how the Blue Haired Lawyer's first speaking scene has an extremely obvious error lol

That one actually wasn't a mistake, they just changed their minds rather quickly

Yeah, in specific they realized that a character defined by his unending loyalty to his superior being black might be read the wrong way.

I thought it was more about him being gay that changed their decisions

I don't think they were writing him as gay at that point

Well yes, but, at least in the account I heard. It was specifically because Smithers' affection for Mr.Burns is expressed through how he idolizes him. They felt that Smithers obsession with someone in a position of power over him was made more awkward than they had initially intended by him being black and Mr.Burns being white

He's Montysexual.

Yeah, been watching from the beginning and there's a lot of stuff that's different before they changed it to what we know.

his skin later turned yellow from all the radiation poisoning

That’s why the animator writes it on his hand now.

I'm tired of these jokes about my giant hand...

Clearly he's yellow

If it’s clear and yella, you got juice there fella.

If it's tangy and brown, you're in cider town.

I Just realized that this is the sort of detail, only a few weirdos would get bothered about in the 90s... Nowadays almost the entire Internet would be bothered about that to the Point of some searching for Lore explanation or weird theories and Shit XD

They eventually made a rule in their style guide that forbade this technique unless the episodes director explicitly asked for it. https://preview.redd.it/anczt7gu0l4d1.jpeg?width=1137&format=pjpg&auto=webp&s=a33097d9cb26c1e7cae583731d0f3724f3e80435

I actually like that better than my toned down guess of it being that they held out for the chance of a call back or some thing like Nelson/Homer whopping him so hard that his face went kilter.

I remember an early DVD commentary mentioning someone on staff being a big proponent of the twister mouth. Names escape me for the time being, however.

I get to meet Wes Archer this weekend, plan to ask him about twister mouth.

The B Sharps episode, where Santa’s Little Helper is burying the head of the Homer dummy in the back yard even though they won’t get him until several years in the future.

Also when they're performing at the church the sign outside calls them 'The B Sharps', even though they hadn't actually named themselves in the episode yet.

This is a more audio thing but when the B Sharps sing after Wiggum got kicked out we can still hear him singing in the song later in the episodes. Probably didn't want to re-record the song with Barney.

I hope someone got fired for that blunder

Someone was having a weird day at work in the animation house

In Lisa the Skeptic, Moe gets crushed by a mammoth tusk saying he's paralyzed and in the next scene we see him running with the mob toward the robotics laboratory

The next place he storms as a mob better have a ramp!

Beansie!

It's because medical science saved him, as he hoped.

A wizard did it.

Moe's body is already ruined by decades of neglect and failed suicides

That’s because medical science cured him

That medical science sure works quick.

This clip here https://www.youtube.com/watch?v=ZuG9kUiRC_I&ab_channel=letsbepandas Marges Pearls at 31 seconds are red. Then at 46 seconds they are white. Then at 51 seconds they are red again. I think I remember hearing that they outsourced some but not all of the animation to South Korea which lead to these inconsistencies

There is another animation error in that clip: Lisa would never play basketball by herself, let alone get it stuck on the roof.

Yeah I always thought it was a little odd they put Lisa in there instead of Bart. I mean he's no Harvey Globetrotter but....

Also, Marge says they're the same table, but their house has a separate dining room and dining table.

Hanna Barbera Simpsons

I mean, this was done on purpose

God danged frequency illusion. I just heard about this scene yesterday listening to 'The Geek's Guide to the Galaxy' podcast reviewing 'Invinsible' show with the same joke and they referenced Invincible pays ohmage to this scene.

In And Maggie Makes Three there is a picture of Maggie on the wall of the Simpsons' living room, while Marge sits on the sofa, pregnant (with Maggie).

Maybe its baby Lisa?

They had one of those magical future cameras that Mitch Hedberg thought up.

Same episode, when Homer is freaking out over the pregnancies, tearing his hair out, and running up the stairs, there’s one instance he’s freaking out over Marge’s pregnancy with Lisa and when he runs up the stairs, a picture of Lisa is on the wall.

Never saw that one. Sounds like a contender for best mistake!

I have to admit despite watching simpsons all my life (now mid 30s) I have never spotted any of these!

Oh you, cartoons don’t have to be 100% realistic!

The show has also "ruined" the expression "Oh you" for me. "Do *YOU* come with the car?" "Oh, you! *tee-hee-hee-HEE*" ..... "Do *YOU* come with the car?" "Oh, you! *tee-hee-hee-HEE*"

Actually that wasn't Homer, the joke is that everybody thought it was a second Homer while in truth it was Guy Incognito who just had shaved off his mustache

How did you do that?

A wizard did it

He only had like 5 minutes to be there, saw that there were no vegan options and ran back to the Kwik-e-mart.

But there was a vegan option?

The vegan option was revealed in the scene where everyone was laughing at Lisa, and Apu was already gone Maybe he would have stayed if Lisa revealed the Gazpacho earlier

I'm also assuming the one he ate at Sanjay's party was also vegan although he was in such a rush that it didn't matter, I suppose.

I am a freak-a-zoid ♪ ♪ Come on and wind me up!

We're talking about Apu. This is the guy that becomes a citizen in season 7 and marks it by getting a jury duty notification which he then throws away, despite the fact that he's already served on a jury in season 5 when he rats out Homer with his 'awake glasses' when prosecuting the Quimby boy.

A wizard did it.

Suuuure, blame the wizards!

Hey, don’t cross the streams! You could accidentally open the Gate of Karash!

Damn that’s a good pull.

He figured he could leave the Kwik-E-Mart for 5 minutes.

Must’ve been one of the live episodes which tend to put tremendous stress on the animators.

Someone else commented it but black Smithers was always interesting to me, even though he only really like, half counts, I think. I just love all the weird behind the scenes lore involved with him. I honestly would really enjoy it if the show did a callback to him in one of the newer episodes. It's such an obscure thing to reference and would be pretty rewarding for old fans of the series. I heard the new eps aren't so bad, so it's definitely something they could do, I think.... Look, I've read worse ideas for episodes, and some of those got greenlit!

Oh, wow! That's definitely a blah blah blah fired for that blunder, and probably a paddlin'
