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.

He’s definitely not funny. The typical left wing loser whose comments will ensure President Trump is reelected! Don’t they get it?!?!?!
who cares what letterman has to say not I
Dear David, you I didnt think were funny. You cheated on your wife. You look like hell. You were overpaid idiot. Who cares what you have to say. Do live behind gates and protective walls? Just asking no go away.
Who cares what u think? And who even asked U?
HAS-BEEN
Not as ignorant as you
He is hardly one to talk. He lives in a glass house…..he can’t throw stones.
Another idiot just came out trying to get another minute of fame. Go home and let your beard grow, has been!
David You retired because You were never funny, You are ARROGANT, And you were always a loser. Could not ever beat Jay and Fallon was going to blow you out of the water LOSER
Birds of a feather, flock together! Cuckoo birds!
