With the return of ABC's Dancing with the Stars now a week away, the gambling site BoDog.com has started to accept bets on whether celeb hoofer Heather Mills' prosthetic leg will fly off during competition. As articulated by the site, the appendage "must fall off, not be purposely taken off, during a dance routine for all 'yes' wagers to be graded a win." Thus far, "no" is the heavy favorite, and Mills herself told Extra last week that such a mishap is "very, very unlikely," so bet carefully lest you (here it comes... ) lose an arm and a leg of your own.
