I bet some people made a ton of money on yesterday.
A while back I read a novel where one of the characters was a full-time shyster, the kind who sells fake college diplomas and such. He made himself into a television preacher and every few months he announced the end of the World. His customers then sent him extra money to buy their way into heaven, and when "Doomsday" arrived the shyster invented a "reprieve". This went on indefinitely. So I figure yesterday was a huge payday for some such charlatans!
(The amusing part being the fact that there really are people so gullible. Schadenfreude, you know.
