Watch: Letterman rocks insane beard at Capitals-Penguins game

David Letterman has one hell of a playoff beard.

The former King of Late Night took in Game 1 Thursday between the Washington Capitals and Pittsburgh Penguins where he - and his incredible beard - cheered on the hometown Capitals.

While he may be a Capitals fan, it's no question he would clearly fit in more in San Jose.
