Does anyone remember this documentary about comedy?

Question

There was this docomentary which was more comedy than documentary. It showed like a history of political comedy in america, I remember it featuring a bit of Richard Pryor, George Carlin and the tall long faced guy from 'Homicide' and 'Get on the bus'; the driver who stopped half way through the journey, because he was Jewish and couldn't go on because of all of the religeous tension. It was a great and very funny documentary; I was in stiches. Also, what's the name of that guy from Homicide and Get on the bus?
