10. "Time And Punishment" (Treehouse Of Horror V, 1994)

In this parody of Ray Bradbury’s novel,A Sound Of Thunder, Homer inadvertently creates a time machine after attempting to fix a toaster. When he is sent back to the Jurassic period, he realizes that anything he touches or disrupts will change the future in horrifying ways. Naturally, he wastes no time accidentally killing numerous dinosaurs, insects, and fish during his brief stint in the past.

This leads to a series of hilarious alternate realities, including one disturbing future where Maggie is a homicidal maniac who sounds just like James Earl Jones. This segment is one of the best Simpsons episodes during a time when the show was at its creative peak.
