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.

Your view if our President is simply redundant of the rest of Americans that put him in office. I guess you like cads who keep lying and stealing from us. Hillary that horrible human would of been your choice, wake up u old fool.
Hey letterman, STFU ! IGNORANT IDIOT !
Maybe some people think you are ignorant sir.
Trump is about emotion where people are at wits end of being hurt and no one protects them.
Same$#%&!@*you always were
And that comes from a wannabe , arrogant dictator himself. He’s a washed up Rip Van Winkle. Go back to sleep you unlikeable jerk.
This really says more about Letterman than it does Trump. Letterman is a giant horses butt always has been always will be
THIS GUY LOOKS LIKE WHAT HE IS AN OLD DUST MOPE
Who cares what David Letterman thinks now in his very old age is he forgetting about the flipping mess OBAMA The Corrupt did to America 8 years prior not a word be he can bad mouth our current President who has only been in Office for 5 months!
A talentless elitist.
