Simpsons Treehouse Of Horror #21

"Ned Flanders believes he has missed 'The Rapture' until he discovers that everyone who has been left behind is left-handed! Then, Apu accidentally receives a shipment of adorable gremlins intended for the sorcery shop a few doors down the block; unfortunately, he doesn't read the warning that tells him not to feed them Squishees after midnight. And visit the 'metropolitan' world of Fritz Lang (Simpsons-style), when the idle rich championed by Mr. Burns clash with the working poor led by Marge Simpson."
