i would like to see McDreamy aka Patrick Dempsey see on the challenge, given his determination to win as a racing driver

maybe american speed skater Shani Davis would be interesting

McKayla Maroney would be awesome too, with her rhythmical strength, great eye for balance as gymnast

maybe a Dennis Rodman for the entertainment factor too

maybe a YouTube meme like Rebecca black since she'll do anything for some attention, popularity, just for laughs
