K so, back when we all had AIM, everyone was putting these "how well do you know me" quizzes in their profiles. When you finished talking one, it showed how many you got right/wrong, as well as the results for everyone else who took it.
There was this mystery screenname getting 100% on every last one of our quizzes. No one ever figured out who it was. It's like urban legend for us.
So if i could learn any one truth about human history, it would be the identity of that screen name.
