This Archive of American TV interview (the full version can be found at the Archive’s website) was conducted in late 2007, about six months before his death. In this excerpt, Carlin does a hilarious imitation of Ed Sullivan around the 4 minute mark.

The term comic genius is an understatement with this fellow. His influence on comedy can be felt everyday. Hell, his influence permeates throughout The Daily Show.
