Matt Kenseth and Carl Edwards

You might think that the time for two race car drivers who don't like each other to battle it out would be when they're, well, in their cars. But for a moment in 2007, trading paint wasn't enough for Roush Fenway Racing teammates Matt Kenseth and Carl Edwards, and they decided to go hand to hand (on camera, no less). Now, apparently, it's all good, and that time Edwards tried to take Kenseth's head off, and Kenseth tried to make the world believe Edwards was a bi-polar thug is long forgotten.
