I just figured it out... Burt Steele started out as an AI project created by Morey to study clutchfans and predict fan sentiment. But the AI went rouge by opening up a twitter account and pretending to be an insider after it learned our worst instincts. This is clearly the only explaination...

Or if you're drunk and confess, make sure the people around you are so drunk they will forget the next day.
