Trampolines in theory seem like a heckuva lot of fun. Given that they're typically made of fabric pulled tight by an array of coiled springs, what could possibly go wrong?

Quite a bit, it turns out.

In this compilation of trampoline fails, a gymnast makes a critical error in judgment and crashes to the floor, a man gets his leg stuck in a basketball hoop, and more than several people have spectacular (and painful-looking) landings on the metal frames of their trampolines. Ouch.

Yep, although trampoline-like devices have been around for hundreds of years, it sure doesn't seem like we've made them any safer.

But all of these mishaps pale in comparison to a stunt involving a roof, a trampoline and an inground pool. We won't spoil the ending for you, but suffice to say the man in question won't be needing dermabrasion treatments anytime soon.
