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.

Still looks like an$#%&!@*
Shut up and stay retired, because nobody cares what you think.
Asshat Letterman
dink
A beard doesn’t make him an intellectual
santa should give you your wish and go back to the north pole.
Poor old Dave, cash doesn’t equal brains. Nobody wants to hear the ignorance of your limited perspectives.
Shut up and go away
You’re nonsense David Letterman
Go back under your rock, Has-been Letterman
