The accidents are either amusing or terrifying.
The ones that have me scratching my head are the ones like the guy at about 4:58 who sticks his head into a rapidly spinning ceiling fan. I think he's auditioning for a Darwin Award.

I note that when it's really bad it involves skateboarding, people saying "allah Akbar", Russians or alcohol.
.......and it almost always involves people saying "Watch this!"
Back when I used to watch the occasional slasher flick, it would have taken 10 of those films to make me clench and wince and otherwise physically react as often as I did watching this clip.
I'm still wondering what those Russians were thinking at 2:10?
