Duncan's Big Day Out - S1.E12

On the way to a concert, the Truckstoppers convince Duncan, WC's loyal limo driver, to visit his old town that he has fond memories of. As they arrive in Greensburg, the Truckstoppers and Duncan are shocked to find the citizens of the town turn on them on sight. The Truckstoppers learn that the town was destroyed by WC Moore, in order to find the material Berkonium, and was sucked dry and left in an unpleasant state, with Duncan regretfully helping WC along the way in order to achieve his goal.
