well the dumbest thing i ever did was well here it goes........ ok me and my older bro were being dumbasses and he bought 2 trampolines (yes hes a rich -blam!- and i hate him for it) and we set them about 4 feet apart....we were jumping between them when we desided to do some thing stupid....we got a ladder(one that supports its self) and we would jump off of it and do tricks across the gap and my older bro (at the time he was 19) did a front flip across the gap so i tried it and i bounced and did a half flip when i landed square on my back i didn't break anything but it did hurt like hell and i did have a swelled up back for a couple of weeks.. what stupid -blam!- have you done?
