I can't touch that one, but I did send my sister to the emergency room because of a potato gun fight when we where kids.
We wheren't shooting at each other, but she had came after me because I had stole her hair spray to use it. She is 5 years older than me, and could easily beat the crap outta me at the time. she was chasing, I turned around and shot and intended to just scare her, but shot mr potato right into her leg
