I completely destroyed the tendons in my ankle - couldn't out any weight on it for a good month.....
No bodily harm, but I hurt my video game system (which we can all relate to).
I went to my friend's house to a party and was bringing my 360 stuff for the next day when we were just planning on hanging out and gaming. Needless to say, I somehow managed to drop my harddrive 4 feet into a snowbank. After that, I accidentally threw it down his flight of unfinished stairs (they were just the wood, so no carpet yet) which absolutely wrecked it.
I lost everything on the harddrive. :(
I was trying to sleep after drinking heavily once and suddenly had to throw up. So I tried to roll out of bed really fast but managed to faceplant on the nightstand pretty hard. Needless to say, the next day I was hung over with a dirty carpet and a big bruise on my face.
Was walking quickly down the hall all energized about whatever was gonna happen when I got through that door and I smashed the outside of my right foot into the door frame. This was about 4 years ago at this point and I'm pretty sure I broke something at the time because I still feel a weird tingle when I put pressure on that foot the wrong way, and it'll also go numb from circulation if I've got my legs folded up or across in anyway. I was a Jimmy John's delivery driver at the time and I had to walk on the side of my foot for nearly two weeks and could barely press the gas pedal.
I've woken up after a long day/night of drinking with lots of bruises and small cuts all over that I can never remember happening. Worst was probably a solid 3 inch cut across my thigh that I still don't know how it happened. Once saw a friend climb on to the roof of a frat house and then we found a dirty old mattress laying around and 4 of us held it and then chanted his name until he jumped on to it. He was fine though, I think. At the same party another dude walked into a wooden fence so hard he tore the whole thing down. It was pretty fun!
never injures myself besides the hangover the day after. The worst I have done though is come back from a messy night deciding i should watch something on my laptop. Woke up to a broken laptop and had to open it up to realize I had puked on it. Cleaned that sucker out and gave it a day to dry and that guy is still fine
