          | When 
            Durham arrives at the Dingleberry obstacle, the Official chides Chris 
            for being late, indicating that he has already started the clock. 
            Chris doesn't break stride. He accelerates into the obstacle, sending 
            mud and debris flying in all directions. He reaches a steep drop-off 
            and Scully directs him to drive over it even though the line doesn't 
            look so good. Too little time remains on the clock for Chris and Tim 
            to consider backing up and trying a different line. As he comes down 
            from the ledge, the rear tires lift well off the rocks and the rig 
            lands hard. When it settles, Chris discovers that his transmission 
            has quit pulling. He has about 15 feet to go to complete the obstacle. |  |
