On Memorial Day weekend, NASCAR's bad boy is trying to own the title of baddest man on the track by pulling off racing's version of an IronMan triathlon. In a single day, he'll try and race in the Indianapolis 500 and the Coca-Cola 600, with a race or two against the clock thrown in. (AP Photo/Orlin Wagner, File)
