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.

Clueless.
Letterman, we deplorables really need your advice. You dumb$#%&!@* Trump forgot more about running a business/country than you will ever now. Now crawl back under your rock and stay there.
Yeah you should be so ignorant David Letterman
He is Just another kook in life…
Wow! Looks like Dementia has started
Arrogant Elite Globalist.
He’s a self-righteous fool at best
So he is cunning and ignorant all at the same time 🙂
Letterman is ignorant and arrogant.
Never ever was funny………just ignorant
