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.

Sums ass
Dumb ass
Shut the$#%&!@*up santa
Really?
Letterman is the Ignorant one; was only book smart growing up and after. He never tells the small town he really is from.
He has his nerve. Remember when he admitted to having sec with his staffers and wrote out a check to keep them quiet? How soon he forgets his own sins.
Letterman s a lazy ,stupid idiot
Just to reflect back and think about the many nights I stayed up to watch your show and now realise just what a rich, liberal, dumb, stupid, ignorant fool you turned out to be. I figure JOHNNY Carson is flipping in his grave now. So go hide somewhere and stay hid.
He lost it awhile ago –
shut up Letterman didn’t ever like you
