The show won't air until this late summer, but the two performers are out and about filming episodes right now. Last week, the two and the crew were in Texas where they, among other events, needed to find ways to refuel their biodiesel tour buses. The stunt was to outsell the other at Keller's Drive-In. By selling a lot of greasy food to customers, the kitchen could make more grease, which could then be turned into the biofuel. Ludacris offered $20 to the person who could eat the most corn dogs. Looks like they've got the recycling angle down, but not the reduce part. Maybe next season.
