South Park: 10 Worst Things That Have Ever Happened To Butters
8. Made To Believe The World Had Ended - Casa Bonita
Cartman is a master manipulator, though even if he wasn't it wouldn't be hard to trick Butters into believing the world was ending. And that's exactly what Cartman achieved when he wanted to go to Kyle's birthday party.
Eric convinced Butters that a meteor was on a collision course with Earth, and to survive he had to hide in a bomb shelter. Not only that but when little Leopold was reported missing, Cartman said the meteor had hit, that the town was destroyed and he needed to stay hidden from the flesh eating cannibals.
He got lucky when Butters got trapped in a fridge and shipped off to the dump, where all the refuse and trash made Butters truly believe the world had ended and everyone was dead. He got to work rebuilding society until a garbage lady discovered him and let him know all was well.
He went through the whole ordeal believing his friend sacrificed himself for the greater good, but in the end looked like a gullible idiot with his pants round his ankles.
