MY favorite TUF guy would have to be....
From season 1: Chris Leben; even though he didn't make it he still was a great addition and his antics were very funny
My Shit fighters from season 1 are: Koscheck and Southworth (assholes)
From season 2: Didn't follow that season very closely
Season 3: Soloman Hutcherson
Shit List: Rory Singer (because he's super gay and annoying) Danny Abaddi (I just didn't like him)
