Former model Rachel Hunter will most likely win if breast size or a personal history of blowing famous guys figures into voting, though dark horse Antonio Sabato Jr. can't be counted out on either.

These brave folks all will attempt to perform Big Top style acts then have their performances judged and voted on "Idol"-style. First prize is a shred of human dignity.
Originally, they were supposed to get more than a shred but producers were afraid that like severely malnourished Ethiopian children when first given real food by Oxfam workers, these people could die if given too much as they have been without it for most of their lives.
It's suprising to me that for years the ASPCA railed against the cruelty and indignity that animals were made to suffer at the hands of unscrupulous circus trainers in order to perform, yet no one has stepped in to stop these people's agents from doing whatever it is they have to do to keep convincing these folks that they have talent and/or salvagable careers.
Though this show is pretty low on the food chain, Fox is already working on something to match it and go a few rungs lower. Look for "So You Think You Can Fart?," "Are You More Emotionally Developed Than A Porn Star?," and "Celebrity Bukakke Challenge" next fall.
