Treehouse of Horror XX

This year’s triple threat of Halloween hilarity sees zombies escaping from their captures and walking the streets of Springfield, Bart and Lisa caught in a murder pact where they both have to kill their own teacher, everyone in Springfield becomes hateful zombies thanks to Krusty Burger’s newest burger, and Homer accidentally falls on a spike and Moe using the opportunity to use Homer’s blood in his beer (somehow making the beer even better).
