If you watch it a little closer, it appears that he was run over by an oncoming car just as he fell out the door. This is about as unfunny as it gets, I'm afraid. He was probably killed.
I already saw that clip on another site w/ extreme videos, I have no idea why someone would want to share a video of their friend getting killed or horribly injured w/ millions of strangers on the web, there are an alarming number of these reality snuff films out there.
