Comic W. Kamau Bell is taking his political and social satire to CNN, where he's hosting a new docu-series called 'United Shades of America.' He describes himself as having made a living finding humor in the parts of America he doesn't understand. The original premise of the series was a black guy goes places he shouldn't or you wouldn't expect him to go.  Bell formerly hosted a series of political satire called 'Totally Biased,' which was on the FX and FXX Networks.
