I think it was on one of those MLP avatar threads. Mind you, my memory is worse than those songs sung by that tiny ***** with the bad haircut, so I don't know.
Anyhow, I just discovered something. Someone on the forums has an account named "Herobrine". I would probably choose that guy just to find out who the man behind the ghost in the machine is. I AM AWARE THAT HEROBRINE IS NOT REAL, YOU DO NOT NEED TO REMIND ME ABOUT IT.
