When I was in junior high, I was playing around underneath a cot and ended up chipping a tooth on the metal frame. I also have a scar from when I was 4 and ran into a mailbox. I once bounced off a tree while sledding down a hill on an inner tube.
Last night, I earned another injury that resulted directly from behavior that was not particularly bright or responsible. I will preface this by saying that I was already drunk. I'd drained a flask of Bacardi and had finished about four beers, plus whatever Everclear I had absorbed through my cheeks. Here's what we were doing:
Get a mouth full of grain alcohol. Spray it atomizer-style into a tiki torch. Try not to hit anything flammable with your firey spit.
Long story short, my aim sucks and I lit my hand on fire.
But it's fine now, just first and second degree burns. Didn't even lose any arm hair.
