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.

Letterman your a moron
Billionaire Trump is ignorant? Yeah – he got all that money by knowing nothing. He got the majority of Americans to vote for him because they thought he was simple minded. Letterman you are the ignorant one. You are also a self-absorbed fool.
Have you looked in a mirror lately Letterman??
You’re IRRELEVANT!
F**k him he is an asshole
More of an American than your a## punk
Ignorance is bliss old man look in the mirror!! You look like the unibomber!
Look in the mirror!
Look at tbis,face of a man who calls the President illiterate. He is not fit to shine Trumps shoes.
Not funny Dave…you dumb$#%&!@*
