A slow build in a sketch with Richard Pryor playing a straight-faced president.  Back in the 70's, just the premise of Richard Pryor was hilarious, as you can hear from the audience reactions.  In classic Richrd Pryor tact, he starts the press conference conservative and calm, then starts to let the Angry Brother slip out.  The odd bit of prescient premise aside, some of this humor about 70's Black Soul Power is pretty much what many white people have feared and expected about Obama.  While many references seem decades old, the bit about the NFL getting more black quarterbacks, black coaches, and black team owners is strikingly timely.
