Damn, before my pc got formatted, I had a video of a guy who is blowing air to a...sort of inflable water thing, like a plastic raft or something, and suddenly, a kid jumps in it, and the air gets back to the head of the blowing guy (sounds strange ) and makes his head to explode!
It's fake of course : but is damn funny, I'l try to search it in my cd's, hopefully I will find it and I promise to upload it
