it depends...

if the challenge requires a lot of running/jumping, I'm rooting for the hottie with a nice rack.

I also like to root for the challenge monsters rupert, james, ozzy but get frustrated when their political/social game blows so much.

I always hate the lazy useless fucks like cirie, kathy or chet.... leeches always frustrate me however chet is entertaining, so I would like to see him continue on.
