All I can say to that Cal_kashi is wow. The best I've done is been impaled by rusty screws after I fell off a wooden swing, I'd actually say I was fortunate because the scars are very high up the inside of my thigh. Pretty nasty looking ones for a while too.

Once I tripped into a woodpile while it was dark out and busted my lip open for probably an hour and a half. I used half a paper towel roll to get it to stop.

I never seemed to break anything, I just get cuts all the time.

Other than those two, its just the standard cuts and abrasions, flipped over the handlebars of my bike when I was six, lots of abrasions on that one, and I still carry a lot of those scars. The criss-crossing scars from cardboard papercuts I got from working at a packing warehouse for a while (though they kinda faded recently).

I did smash my finger in the door just two days ago though, nothing really serious. But with those kinds of injuries, I think Cal wins the prize.
