The internet is full of 'epic fails' as the kids like to say, so here's a compilation of a bunch of people almost getting seriously hurt.
If you were looking for a list of things that you definitely shouldn't try, then look no further than pretty much everything in this video. Some of them are obvious like don't run out in to the middle of the road, or always stop at a red light, while others are a little bit more unusual, like don't backflip off the roof of your house into the pool.
All of them have one thing in common, and it's that everyone ended up OK. Just. If you're of a nervous disposition, this video should be watched through your fingers as you cover your face in terror. Enjoy! There's some slightly NSFW language in here too, just as a warning.
So yeah, like we said, don't try any of these at home, or anywhere really.
