Richard Pryor!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Nobody remembers Richard Pyror? You ever hear of Steve Harvey? He is a famous guy currently with a TV show and specials. He is basically channeling Richard Pryor. Walks and talks like him, facial expression like him, voice cadence like Richard Pryor.
