OBSTACLE COURSE
DWTS loves itself a challenge. Whether it's season 5's Mark Cuban dancing on a newly replaced hip (owwww), season 4's Heather Mills funkin' up the jive with a prosthetic leg , or season 3's Jerry Springer scraping his carcass over the giant hurdle involved in being Jerry Springer, the producers can't get enough of stars who overcome significant obstacles in order to get flung across the ballroom. Perhaps most impressively, in season 6, actress Marlee Matlin (pictured) couldn't hear the music, so she felt it through her partner Fabian instead. Cristián de la Fuente made it to the season 6 finals with just one arm! Misty May-Treanor, who underwent surgery after injuring her Achilles tendon last week, is practically the first DWTS contestant to show some restraint: She'll finish out the season from the audience — occasionally waving one of her crutches to demonstrate ''beautiful lines.''
