David Letterman might be on your television every night, but the guy is definitely showing us how to do retirement the correct way. The former Late Show host, who probably doesn't care what you think about his running outfit, showed up to this year's Indianapolis 500 to root on his Rahal Letterman Lanigan Racing driver, Graham Rahal. Letterman, with his beard, sunglasses, and racing suit, looked like the picture of enjoying post-career life. And what's even better is that Letterman was supposedly drunk.
You keep doing you, Dave.
