Retired Late Night host David Letterman has been out of the spotlight for about a year now after his retirement from television, but he’s still all-in when it comes to his race team. Over the weekend, Letterman was a guest on Sports Center at the Indianapolis 500 and it seems as though he’s relaxing and enjoying retirement a bit! First off, he’s nearly unrecognizable with a massive, white Santa Claus-esqu beard! And secondly, he’s definitely been hitting the sauce, as he admitted to in the clip below, which was on live television!
