Just like when I see an actor play a paraplegic. Im one and can call it in seconds if theyre real. Only one I can think of thats real is the black guy that was on tv show "Ed" and now something else. I was in balcony seating with him to watch "Aida" with Tony Braxton on broadway yrs ago. Didnt know who he was till I saw him on the show. Was a shocker.
