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.

Mind your business scumbag
Bill Clinton tried. Like hell in fact.
Dave!! you need to stick with fuuny stuff….your opinions are not welcome or wanted….
First Letterman never was that funny. Second, this spoiled$#%&!@*Hollywood type has no clue on what it takes to run a country. He should just say “thank you and be in his way l”.
Letterman. Your not a genius either. Shut up!
Letterman you’re an old comedian not a scholar…
Pos drop dead.
Asswipe forever and before. Why doesn’t he share his wealth .
I could care less what Letterman thinks now or when he was on tv, never watched him. He was never funny!
And who was unable to cope with life oh Mr Brilliant?
