The Simpsons: 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).

Episode Notes
This episode ended with the entire Simpsons cast in Moe's Tavern singing a few lines that fit perfectly into the instrumental Simpsons theme tune. The lyrics go something like this:

"We hope you enjoyed this year's Halloween show...
She has a foreign number, it's X"

and then two X's drop down from the "studio"'s ceiling, signaling to the viewers that this is the 20th Treehouse of Horror (X=10, XX=10+10, XX=20)

This is the first Treehouse of Horror to air before Halloween in almost 10 years, due to such episodes being pushed back due to the World Series Games.



Episode Quotes

Lisa: Apu, how did you survive?
Apu: Well, as a vegetarian, I did not consume any tainted meat and as a convenience store owner, I am armed to the teeth.

Kang: This is the best musical I've seen in lightyears!
Kodos: Light years measure distance, not time!
