Campy commercials with F1 drivers are just a bit of sidework for NASCAR champion and all-around badass Tony Stewart. From 24 Hours of Lemons to dirt track sprint cars, if there's a race in Stewart's vicinity, chances are he's behind the wheel.

Last night, for example, Stewart was racing a sprint car at Ohsweken Speedway in Ontario, Canada. Everything was going pretty well until Stewart, chasing Shane Stewart (presumably no relation) who had just passed him, edged too high up the track, grazed the berm, and went cartwheeling down the fence line, as sprint cars are wont to do.

The result? One fairly mangled race car towed off course, and an uninjured Tony Stewart. Well done, Smoke. Next time, maybe keep the sticky side down?
