Maggie gets possessed by a demon; Lisa discovers a creepy/perfect version of her family in an alternative universe; Homer cannibalizes himself.
Did You Know?
The part of Lisa appearing on stage to warn people of the disturbing content in the third segment is based off the warnings that were used at the beginning of the first five Treehouse of Horror episodes. This is also the first time this warning had been used in 23 years, since the airing of Season 6's Treehouse of Horror V in 1994. See more
