||In Thrillbilles episode 8, Travis Pastrana's cousin, Special Greg, takes on Robert Pastrana and a couple of his buddies, plus Streetbike Tommy, in a hilarious four round boxing match. Then, Thrillbillie, Jim Dechamp, tries a front flip on his mountain bike, lands back first on bricks, and somehow walks away. Travis' best buddy and Freestyle MX champion, Cowboy Kenny Bartram, is profiled by members of the crew. And finally, Travis achieves yet another first by completing the first double back flip on a motorcycle. Shot in California, Maryland, Utah, and Washington, Jeremy Rawle and Gregg Godfrey (as Refus and Sprocket, respectively) act as hosts to help tell their stories of success and failure. These stories, the mysterious Tenacious J*s observations, and more mayhem in the episode number 8.
