Homer fears the Biblical end of days is coming after watching a movie and seeing what he thinks are signs of the Apocalypse.

!! Tropes:

* AuthorTract: The movie ''Left Below'':
-->'''Thompson''': It's the Rapture, Shauna, the Rapture! The virtuous have gone to {{Heaven}}, and the rest of us have been... [[Literature/LeftBehind Left Below]]! We were fools! And because we rejected God (tacitly accepting Satan), we must suffer through the Apocalypse.\\
'''Buddhist Monk''': I thought all religions were a path to God; I was wrong!\\
'''Scientist''': Why did I put my faith in science and technology?!\\
''' Homosexual''': Oh, why did I choose to be gay?!
* TheCuckoolanderWasRight: Homer was right about the Apocalypse happening.
* ShowWithinAShow: ''Left Below'', a parody of ''Literature/LeftBehind''.
* StatusQuoIsGod: God restores the Status Quo by chanting "Deus ex Machina".
* UngratefulBastard: After Homer's first calculations prove incorrect, everyone treats him like a pariah. This wouldn't be so bad, except Homer's initial prediction brought out the best in people like Moe. However, they don't look at the upside, nor do they consider Homer had their best interests at heart. It's made worse when [[Main/KickTheDog Marge throws Homer's corrected calculation back in his face]]. As Homer drives to the Mesa again, [[DiscussedTrope he actually considers this trope]].
