Rich

I was approached by a stranger and told that he could make me rich, as in filthy rich. All I had to do was give him a thousand bucks and I'd get a million-fold in return. Wow! Drooling, I asked him when I'd get the return on my investment. He said when I'm six feet under. Cool! Here's a thousand. Can't wait to kick the bucket and be a billionaire.

Religion: Scamming and getting away with it with promises of eternal reward after one's life is over. Only imbeciles could possibly fall for that... Oh wait!
