Watching those two interviews does seem like an alternate universe from my original perception of the video.
"Tough Thug" really was talking like Stewie Griffin. He still had cornrows, but everything else showed that he appeared to be an articulate gentleman.
Epic Beard Man, however, casually mentions in passing that he knocked his friends teeth out for stealing his cocaine, and clearly hallucinated about "Tough Thug" being a murderer, and threatening him with a knife, etc.
