I don't know if I would say Dale Sr.'s smile, I would go with his grin. I loved it when he would grin because you could just tell that there was something going on inside his head.
Jimmy Spencer has teeth. I thought all those doughnuts would have taken care of that!! lol
I'm with you 88isgreat, I love DJ's smile. Parks is good too, and Tony's smile could light up a bad day anytime. The best smile is when they're in victory lane!
