Jonny Fairplay, Andrew Firestone, Omarosa Manigault-Stallworth, Trishelle Cannatella, and Charla Faddoul compete on behalf of their favorite charities.

Who are these people?
Omarosa Manigault-Stallworth and Charla Faddoul sound like they might be Al Quaeda operatives, but the others?
Ok, I'll take a guess.
Jonny Fairplay - gay porn star, c'mon, the name reeks of gayness, NTTAWWI.
Andrew Firestone - Paris Hilton's date for the Junior Prom. Hilton, Firestone, old money, old money, old money ...
Trishelle Cannatella - African/Italian American princess, eh.
