That's a good way to dislocate your leg.

Adam Miller is well known in the skateboarding world for his creative tricks. Here he pulls off perhaps his best yet. Miller skates towards a set of six stairs, backflips off one skateboard and then lands perfectly on another board placed at the bottom of the stairs

A skier attempts a huge backflip but fails badly.

He needs to work on his form a little bit more.

She might have actually landed it if that dude didn't walk into her mid flip.

Like a Boss...

Look at the size of that Ramp! So many things could have gone wrong here. He lands the backflip though!

Ouch, that left a decent mark. You sir are no Olympian. Fail!

After watching his buddy do a backflip off the wall he decides to show that he can do it too....or not!

That's one way to end up in a wheelchair.
