There was, iirc, once upon a time - a doomsday cult that predicted the imminent end of the world, because God or the aliens or the Mayans had grown tired the profit-making, money-grubbing, inhumane society we had created.
When the predicted dooms-day came and went, the newspaper confronted the leader of the cult - expecting the usual "we recalculated" or "the aliens gave us an 11th hour clemency" or the usual stuff... Instead the leader simply stated that the world had in fact ended as scheduled, but that the world was too caught up in their wickedness to have noticed the change.
I always liked that one. When I hear about a new end-of-the-world prediction now, I just murmur to myself... "What? Again?!"
