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.

Idiot.
Loose the beard grow some hair and just leave forever
This man is the weirdest guy on the planet and has the nerve to talk about the President. What a moron.
You have never made any deference reason why you never replaced Johnny Carson
Wow, he’s let himself go. Or has he? At least he’s still on the cutting edge of brain deficient progressive thinking.
A dictatorship that gives Americans their rights back… have a seat letterman you clown!
I’m so glad he has retired!!!!
The only ignorant person I see is Letterman. Not interested in hearing anything he has to say.
Letterman has never been funny. He made his living making fun of everyone else and now all of a sudden he’s concerned about others? Hypocrite and hateful.
His late night show sucked, stupid
