Sam Kinison, a former Pentecostal preacher turned beret-wearing, bad-boy comedian, is the focus of this tribute from a galaxy of comedic talents who analyze his hard living and the rage-filled comedy that took the entertainment world by storm. Jay Leno, Denis Leary, Chris Rock and others discuss their friendships with him and his unusual but perceptive humor, while clips of Kinison performing live illustrate how effective his screaming style was.
