Amazing Race good guy Chip McAllister (who with wife Kim took home the show's $1 million prize) is a real champ. As a teen, McAllister, then working in a supermarket, was tapped to play the young Cassius Clay (a.k.a. Muhammad Ali) in the 1977 biopic The Greatest. A modest acting career followed (including 1986's short-lived CBS sitcom Better Days) before he decided on a more stable career in information technology. So how about a comeback? ''I could do a lifestyle-type show with Kim,'' says McAllister. ''Something where I could just give away stuff. I love to make people happy.'' Heads up, Oprah.
