Ask AI: A season eleven episode of The Simpsons where Marge Simpson gains elastic powers via the Power Plant.

It sounds like you're referring to the "Treehouse of Horror X," which is the fourth episode of the eleventh season of *The Simpsons*. In one of the segments titled "Desperately Xeeking Xena," Marge doesn't gain elastic powers. Instead, Bart and Lisa do after being exposed to radiation. They become superheroes called "Stretch Dude" and "Clobber Girl." Marge does not take part in gaining powers or the superhero theme in this segment.

It seems like you're mixing up a few things, as there isn't an episode in season 11 of The Simpsons where Marge gains elastic powers. However, in the 17th episode of season 11, titled "Bart to the Future," we do see a vision of the future where Lisa is president. Your reference of Marge gaining elastic powers is actually from the "Treehouse of Horror" series. Specifically, this happens in "Treehouse of Horror XIII: Stretch Dude and Clobber Girl," but it's Bart who becomes the stretchy 'Stretch Dude' and Lisa who becomes super-strong 'Clobber Girl,' rather than Marge. Hang on for more futuristic and mystical episodes of the Simpsons and remember that The Simpsons is known for its satirical outlook towards life, so enjoy the fun that comes with every episode!
