I simply love Steve Martin, always have. He is hilarious in a somewhat undestated way. Billy Crystal had some wonderful skits on SNL like Fernando. I still cannot watch them without dying laughing. Robin Williams is just plain crazy at times and has a rather unique outlook on life and Chevy Chase, well, is about as funny as a sucking chest wound. He is never been funny, save perhaps his Gerald Ford impersonations on SNL. Those were pretty epic. He is a bitter, vile, vitriolic and very unfunny little man. And his ugliness on the inside has made him very ugly on the outside.
