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.

Kindly looking exterior?
Are you kidding?
He looks awful, and that’s putting it kindly, not to mention he is brainless
Letyerman, you are a has-been
Some of them are brain dead. They wake up and say “oh gosh I can put my name out there for one more time”. Sorry for their stupidity, they still need someone to write their lines.
Go away old ugly pervert!
IDIOT
Retardo
Oh boy! Letterman, the guru of all ignorance….. tsk…tsk… tsk…
Dementia sucks, huh Dave.
Much smarter than you dave! You were a mediocre comedian!
This idiot is a bitter jealous old man he can’t see straight because of his envy of our President. He needs to crawl back under the rock he came from
