Joey seems the funniest and most down to earth. I know someone from Seattle and I can see similarities in their personalities. So I'm hoping she doesn't become horrible while in the house!
Christine seems fun and smart and knows the game. Zach will either be horrible or amazing, he's clearly playing up the douchey persona, so it'll be interesting to see how he plays it when he's in the house.
Having just watched all the interviews, Christine and Derrick stood out most for me at the moment. I'm really hoping not to get Caleb or Cody on the sweepstake.
