10 Worst Things Lisa Simpson Has Ever Done
4. Manipulating Bart’s Coma
This move was incredibly out of character for Lisa and absolutely vile.
It’s only being kept out of the top three because she feels exceedingly guilty about it, and it gives us a great episode... even if like most modern day ones, it never fully delivers on its potential.
The Season 29 finale, Flanders’ Ladder, sees Bart fall into a coma as he’s struck by lightning. Lisa decides to take her revenge on him by whispering malicious things into his ear, manipulating his coma addled brain into giving him terrifying nightmares.
Aside from the fact this cruelty is way out of line for any version of Lisa, it’s such a disproportionate revenge as well. She’s mad at Bart for making her watch one of those scary maze videos where the monster jumps out at you.
It’s a pretty tame prank that happens all the time between brother and sister, and hardly warrants this reaction. Considering the episode came in 2018, it’s severely dated too.
The trick ends up causing Bart to have nightmares, including being haunted by Maude Flanders. It’s not even a one time mistake by Lisa either, she continuously does it until Dr Hibbert warns her it could damage him permanently.
