IIRC he interviewed a wrestler pre-match, and when the guy mentioned kayfabe Louis says "So it's not a real sport is it" which is the worst thing you can possibly say. So they invited him to join a training session so they could Sgt Hartman his ass.
It's real like the circus is real. My only problem with it is that the really famous guys mostly seem to be clumsy meat heads, but the little Japanese and Mexican guys are amazing.
My favorite part of this entire piece is the very beginning. Raven is sitting in an airport and Louis is all "I'm doing a film on wrestling" and Raven is all "Oh yeah? Well do you know who I am? No? Then you have no idea what the fuck you're even talking about."
