The Simpsons has been around for 29 years now.
But even though it's a solid TV staple in our homes it still makes the occasional error.
Like when there was a picture of Maggie hanging up on the wall, in the episode that Marge is pregnant with Maggie.
Or when Smithers changed ethnicity a few episodes into the season.
Maybe you can't shake off how Marge and Homer's backstory is constantly changing.
There's probably a whole load more that we, and the Simpsons creators, have missed too!
