The Simpsons: 8 Episodes We Never Got To See

8. Lisa The Scientopteran 

The Simpsons has been no stranger to controversy over the years, having poked fun at everything from organised religion to Hollywood, and government officials to billionaires, but this could-have-been Golden Age episode was apparently a step too far for the showrunners to go ahead with.

Originally meant to air during the show's eighth season, "Lisa the Scientopteran" was written by frequent show writer George Meyer, and would have found Lisa joining a movement strikingly similar to Scientology.

Despite some of the much more taboo topics The Simpsons have tackled over the years, Meyer's script was never picked up for production, left behind because of "legal ramifications" and the fact that "at least a couple of the staff/cast would've felt personally attacked by the episode."

Given the fact that Bart voice actress Nancy Cartwright is a Scientologist, it was probably a good move to leave the episode behind. We all saw what happened with Isaac Hayes on South Park, after all.
