My original username was Wilber7. However the username lock down was announced to where you couldn't freely change your username (yeah we used to be able to do that), so I changed it to something cooler and without numbers. I thought The-Great-One sounded nifty. It has stuck ever since.
Despite being a wrestling fan, I did not base it off The Rock. Despite enjoying ice hockey, I did not base it off Wayne Gretzky. Despite enjoying comedy, I did not base it off Jackie Gleason. Despite enjoying dark humor every now and then, I did not base it off Adolf Hitler.
