Ever hurt yourself stupidly?

I've always liked to climb things, which has led to no end of trouble. When I was five, I climbed a fort my parents had built against our house, and got onto the roof. Combined with the fact that I had just seen Peter Pan, and was convinced I could fly, this then led to me leaping off the top of our house and crashing to the ground (near my sandbox at the time), where I broke my arm in two places (bone popped out at one of them). At five, this was kind of a mixed bag, as it didn't hurt much after the initial event, and the cast was a great weapon to use on other kids at daycare. Unfortunately, the doctor got me with his buzzsaw when he was taking it off, because my skin popped up into the gap, and I ended up with a 3-4" scar along my arm.

More recently, this climbing problem still tends to come out when I'm drunk, and get to feeling I'm a monkey. A few weeks ago, during a party at my friend's place, I got to that point, and figured I would scale the side of his house with my bare hands. Did ok, considering my state, and made it to the second story. Unfortunately, his siding wasn't all that good, and when I grabbed one section, the whole strip came off, sending me out into space. Landed flat on my back in his lawn and couldn't even breath for several seconds. Had a nasty pain in the back of my head for a day, a sore back for several, and thanked my luck I didn't do more.

Jam it back in, in the dark.
