Hicks was constantly facing problems with censorship. In 1984, Hicks was invited to appear on Late Night with David Letterman for the first time. He had a joke that he used frequently in comedy clubs about how he accidentally caused a fellow class-mate to become wheelchair bound. NBC had a policy that no handicapped jokes could be aired on the show, making his stand-up routine difficult to perform without mentioning words such as “wheelchair”. Hicks was disappointed that the TV audience didn’t get to experience the uncensored Bill Hicks that people saw in clubs.
On October 1, 1993, about five months before his death, Hicks was scheduled to appear on Late Show with David Letterman, his twelfth appearance on a Letterman late night show but his entire performance was removed from the broadcast — then the only occasion where a comedian’s entire routine was cut after taping. Hicks’ stand-up routine was removed from the show allegedly because Letterman and his producer were nervous about Hicks’ religious jokes. Hicks said he believed it was due to a pro-life commercial aired during a commercial break. Both the show’s producers and CBS denied responsibility. Hicks expressed his feelings of betrayal in a letter to John Lahr of The New Yorker. Although Letterman later expressed regret at the way Hicks had been handled, Hicks did not appear on the show again. The full account of this incident was featured in a New Yorker profile by Lahr, which was later published as a chapter in Lahr’s book, Light Fantastic.[
Hicks’ mother, Mary, appeared on the January 30, 2009, episode of Late Show. Letterman played Hicks’ routine in its entirety. Letterman took full responsibility for the original censorship and apologized to Mrs. Hicks. Letterman also declared he did not know what he was thinking when he pulled the routine from the original show in 1993. Letterman said, “It says more about me as a guy than it says about Bill because there was absolutely nothing wrong with it.”
