Carl Edwards gave us an interesting revelation at Charlotte Media Day: when he's behind Martin Truex Jr., he starts singing the "NAPA Know-How" song just like the rest of us. And if you know that song, and everyone who's heard it once does, you know it worms its way into your subconscious, wrapping itself around your cerebral cortex waiting to pop out and make you sing it at inopportune times: your wedding, a funeral, driving around a track at 200 mph.
Here's my question, though: we're most often subjected to this ad while we're watching the race. During that time, shouldn't Carl be, you know, racing? Unless he's got a TV feed in his car, which would explain a lot.
