Does it have to be MY injury?, because I love telling this story. My college room mate and I were at a kegger our freshman year when the cops showed up. Being underage and having an aversion to community service, we (along with 50% of the rest of the party) bolted out the back door and started running for the hills. It was dark as all get out, and we were blindly flying through one back yard after another. Suddenly I hear what sounds like somebody falling down hard, and then what sounds like a 6 year old girl screaming. And screaming. And screaming. Suddenly a porch light comes on, and I see my buddy lying face down on the ground in what appears to be somebody's outdoor cactus garden. (Who the f*ck grows a catus garden in Duluth anyway?!) The homeowner is now standing there yelling at us to get out of his cactus garden, but there is no way that's about to happen. My buddy has got an absolute sh*tload of cactus thorns in his face, chest, arms, legs, and back (apparently he rolled pretty good once he hit the ground), and he's not getting up anytime soon, as he can't even open his eyes. Long story short, the homeowner eventually lets us use his phone to call a friend, who comes and takes my buddy to the ER, where they spend the next 6 hours extracting cactus thorns from his body. They only got about 80% of them though, and for the next 3 months or so, he would be sitting there watching tv, scratching his head, and a thorn would pop out and land on the coffee table.
To this day I laugh whenever I think about it. A freaking cactus garden.
