My buddy and I are out back of my house a couple years ago. He's about 20 feet away from me on the phone with his mom and I'm playing with my mini crossbow. It's half the size of a hunting crossbow but still puts bolts through the house walls.
Anyway, out of shear stupidity, he says "Shoot me!" not expecting me to take him seriously. He thought wrong.
Without a shred of hesitation I aimed for his chest and pulled the trigger. A bolt nailed him about an inch below his lower lip going straight to the bone. He hit the dirt in agony.
I definetly regret doing it and have no idea why I did (I'm retarded, maybe?) He said it was like getting hit in the mouth with a baseball bat.
