The Simpsons: 10 Best Ever Treehouse Of Horror Stories
9. Time And Punishment (Treehouse of Horror V)
Playing around with the idea of the butterfly effect, Homer manages to build a working time machine out of a battered toaster and accidentally completely changes the Earths history by sneezing on a dinosaur with a particularly weak constitution, triggering the mass extinction.
Desperately trying to set things straight, he sprints through alternate realities has to make do with a very, very close approximation of the Springfield he knows and loves, aside from the small detail of his family being born with lizards' tongues.
Plus, lest we forget, theres that excellent bit where Homer gets his hand stuck in the toaster twice. Actually, thinking about it, that's pretty much the only reason that this segments in here. It's that good.
