Ozzy is starting to grow on me, up until now Yul has been my favorite and thats from before he found the idol. If he's smart and he does seem so he should go all the way. I wish someone when they found the idol would come up with a dummy and bury it in it's place, that would be fun to watch.
Like a case of bad karma, ever since Ozzy's manipulative, too-clever-by-half scheme to throw a challenge to get rid of Billy, his original tribe has been annihilated. It would seem Ozzy got what he wanted, times four.
In a way, Ozzy's Survivor skills are a litle like Bill Clinton's political skills: He manages to hang on, even as everyone around him gets hurt and eliminated.
