Hicks often discussed popular conspiracy theories in his performances, most notably the assassination of President John F. Kennedy. He mocked the Warren Report and the official version of Lee Harvey Oswald as a "lone nut assassin." He also questioned the guilt of David Koresh and the Branch Davidian compound during the Waco Siege. Hicks would end some of his shows, especially those being recorded in front of larger audiences as albums, with a mock "assassination" of himself on stage, making gunshot sound effects into the microphone while falling to the ground.
