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.

Ass Hat !!
He’s a funnyman–Not a brilliant thinker.
Letterman stfu ya dickhead
Trump’s ignorant yet he hires a man who almost kidnapped his son? Yeah o.k Dave.lol
Growing beard does not make him intelligent to render judgement against the president of theU.S.
Just another insane Liberal..who is a nobody,..thinking he is somebody!
Don’t care what you have to say…as you ignored the mother of your child and the feelings of your interns. You are a pompous Ignorant Jackass.
P.E.N.I.S.
You could be ignorant Mr. Letterman!
Yeah sure he was ignorant enough to be voted in as president.
