Reality TV Show Outcasts: By choice or by force

Billy Bell, 19, has dropped out of "So You Think You Can Dance" due to mononucleosis. In his place, 21-year-old hip-hop dancer Brandon Dumlao will join the Top 20 and will compete Tuesday (Oct. 27) in the season's first performance show. We've also heard that 18-year-old contemporary dancer Noelle Marsh has suffered a knee injury that is supposed to keep her out of the October 27th episode.

Let's check out other premature exits from reality shows, whether by choice or by force.
