If I had to say anything, I'd say it was definitely Dave Dave. At one point he lifts his hands up a little and you can see them on the camera. They are clearly disfigured. If that was Michael and they were able to do that, then good job. But honestly, it is highly unlikely that Michael was disguised as Dave Dave on LKL. In my opinion though, Michael is scripting everything so to speak. Mostly everybody's words seem like Mike's.
