Flip Wilson told Johnny Carson on Flip Wilson/Pat Boone/Tom Dreesen/Dr. Lendon Smith (1976) that he decided to take the role because his kids were big fans of the show and told him that if he was "really somebody", he would appear on The Six Million Dollar Man.
Billy Parker's last line is, "The Devil made me do it." It was Flip Wilson's trademark catchphrase. His best-known character, Geraldine Jones, often used that phrase. It originated from the title of his 1970 comedy album "The Devil Made Me Buy This Dress" and won the 1970 Grammy Award for Best Comedy Recording.
