one of my friends would let his little girl play Mortal Kombat, but he knows full well about the content. I disagree with him on that, but it's his kid, his home and his responsibility. And to be fair, his child is perfectly well adjusted, so who am I to say what's bad for one kid and not the other?
I think I saw that girl the other day. She was standing over a little boy on a playground. Then a disembodied voice yelled out "FINISH HIM!" and she ripped the kid's spine out through his chest. After that she went and picked some daisies and rode away on a beach cruiser.
