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.

Trump is a very smart man so maybe it’s Letterman that is not all that smart??
Idiot
If Trump is ignorant what are you? You were an idiot from the time you went to high school with us in Indianapolis and never improved!
Letterman used to be funny because of his neurosis, now he’s just a neurotic, negative liberal$#%&!@*
Letterman was never funny. Jack Parr, Johnny Carson and Jay Leno were the funny ones, especially Johnny Carson. Oh, the good old days are gone.
Never liked Letterman…
Typical liberal response. You do have a sweet car, though.
Letterman is the ignorant one!! No brains or intelligence!!
