When I was five my neighbors were moving out and just threw a ton of shit out in front of their apartment, including an aluminium picinic table set. My friend Ryan and I thought it would be really cool to fold up the legs of the benches and placing them on two milk crates, use them as catapaults. So Ryan is all set to jump off of a lawn chair and launch some dollhouse the neighbors were throwing out into space and I'm trying to keep the dollhouse balanced on my end of the catapault. Ryan decided to be an impatient bastard and jumped onto the catapault before I had the chance to back away from my end. The serrated edge of the bench springs up, hitting me in the mouth crushing a tooth before slicing up my gums and through my lip and palate. I passed out from blood loss before being rushed to MGH where I had my face stitched back together under shitty anesthesia which did nothing to dull the pain.Another time when I was around the same age I was stung by a swarm of bees at the local pool and fell right on my face as I tried to swat at the bees and run away on the slippery deck. No long term injuries but it fucking hurt.
