New York, NY, June 18, 2008 – In one of the most stunning twists in the history of the Ultimate Fighter™, for the first time defeated three of his housemates for the right to fight for a guaranteed six figure contract with the UFC®, will not be participating in the show’s live finale.
Of course its the guy who pisses himself. I mean seriously a guy who makes the decision to piss his own pants on a regular basis can't really be expected to make the right call regarding anything else.
Jesse Taylor gets kicked off the show AFTER CB gets beat by Amir. Dana is such a huge CB fan that he figures "I'll kick off Jesse for some bullshit and let CB fight Tim." CB fights Tim and beats him. Dana is happy!
