when I was in college, I passed out in my room, did the whole curling up thing, tucked my nuts through to the back between my legs. unlucky though, one of my flatmates took a deck of cards, not in the cardboard case, just a loose set of playing cards, threw them together at me in hopes it would fly everywhere on the way.. didn't happen though. instead, deck of cards stayed together perfectly while in flight, landed with the corner of the deck right onto my left testicle. I woke up crying. I couldn't talk for a week
