For those of you who aren't familiar with Bill Hicks, let us explain: he was a pioneer in stand-up comedy during a time when many comedians refused to probe society deeper than jokes that exclaimed, "Boy, men and women SURE ARE DIFFERENT!"  While Bill probed those differences, he did so in a manner unique to his personal style.  This unaired clip is noticeably more tame than his usual performances, no doubt out of fear of being censored, and yet, that's exactly what happened.  Certainly Letterman was aware of Hicks normal material, and was nervous about airing this clip back in 1993.  It's seemingly tame compared to some of the comics they feature today, but was still banned due to network pressure.  Letterman apologized to Hicks' mother, and is clearly feeling very guilty about his decision.  Finally, we should add that at the time of the original taping, Bill was 31, and had learned only a few months prior that he had pancreatic cancer that had spread to his liver, and would not live much longer.  He passed away in February of 1994, aged 32, just 4 months after Letterman decided not to air this piece.
