Rodger Bingham, the good-hearted 53-year-old high-school teacher nicknamed "Kentucky Joe," became the latest castaway to get voted off Survivor: The Australian Outback. Appearing on The Early Show this morning, a cleaned-up Bingham admitted that he didn't have the cutthroat instincts necessary to win the $1 million jackpot. "I found out that I wasn't as good at actually playing the game as what I thought I might have been," he told host Jane Clayson. Bingham's ouster leaves just four remaining Survivors: Colby, Elisabeth, Keith and Tina.
