I?ve seen a firework char a boy?s face, a group of friends light a fat kid on fire, and a skateboarder who fell so hard he added another joint to his forearm ? all on YouTube. But when I went looking for what the kids in Iran were up to, I found content that YouTube asked me to think twice about.

Do you really want to see this? If you?re sure, entirely positive, absolutely willing to have these images seep into your mind?s gray matter, then go ahead, push the button.
