David Endochrine

David Endochrine is the host of a late night talk show, "The David Endochrine Show." Dr. Wolper arranged for the Joker to appear on an episode of the show despite a huge public uproar. During the interview, Endochrine asked Joker to defend his murdering of about 600 people. Joker declared he was going to kill everyone in the room. When Wolper intervened, the conversation switched to Batman and Joker killed the doctor. After the Joker's fatal Smile Gas was unleashed, Endochrine attempted to hold his breath but eventually fell prey and died onstage.
