David Letterman’s 33-year run on late-night television was marked by his acerbic sense of humor.
Upon retiring in 2015, he’s undergone a metamorphosis into someone almost unrecognizable from the more comedic guy people watched on the “Late Show with David Letterman”.
He’s grown a full beard, which coupled with his balding head, makes him look like a guy wanting to moonlight as a department store Santa Claus.
But beneath that kindly-looking exterior lurks a clearly bitter and troubled man, as evidenced by recent nasty remarks about President Donald Trump.
It’s spelled out on the next page. See how the funny guy seems to have lost his sense of humor.

Moron!!!

Letterman looks like a 90 year old homeless guy with dimentia.
Yeah, douchehat, which is why the press, academia and the arts can tell lies about him every single day. Which is why a process can limp on for a year on flimsy charges that there was some sort of Russian impact on his election. What a joke, Dave.
You are about the biggest mess that was ever on TV you are ignorant
Lying sure makes him age quickly.
Keep quiet, yard gnome!
And so are you, you
idiot
Who cares what this obnoxious jerk babbles? Irrelevant
