Startup Idea : Pay for a Dare

I saw this idea Time machine to go back in time and invest in facebook., and it has already 62 likes. I thought i could write the most stupid idea like Eat sh-it and get rich and i would still get a lot of likes. And i thought a second time about the Eat sh-it and get rich idea and i wondered if people would really pay others to make nasty, painful, embarrasing and dangerous things? And i think yes, they would. So that's my idea: A user sets a price for a dare, and other people pay as much as they want, until it's enough. Or a user offers money for a dare of his choice, and waits for someone to accept. Everyone has to prove his dare with a video. And in the end you have a lot of funny videos to get many views.
