The Simpsons Season 21 Episode 4

The Simpsons Season 21 Episode 4. This year’s triple threat of Halloween hilarity sees Moe using Homer’s blood for beer, Bart and Lisa caught in a murder pact, and everyone in Springfield becoming zombies thanks to Krusty Burger’s latest sandwich. In the 20th anniversary of THE SIMPSONS annual “Treehouse of Horror” Halloween special, three chilling tales of Halloween horror unwind. First, Lisa becomes livid with Miss Hoover, and in a series of homages to classic Hitchcock sets out for deadly revenge. Next, Krusty’s latest fast-food sandwich transforms news anchor Kent Brockman into an enraged zombie and twenty-eight days later, cannibal zombies have overrun Springfield. In the final frightening fable, Homer accidentally falls through a trapdoor in Moe’s tavern and impales himself on the pipes of Moe’s microbrewery. Moe serves the barflies a glass of delicious beer flavored with Homer’s blood and Homer, now half-man, half-brewing apparatus, returns for vengeance in the “Treehouse of Horror XX”
