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.

Hussein was the puppet prince. I wish we had “Resisted” for 8 years.
IF TRUMP IS SO IGNORANT, WHY ARENT YOU OUR PRESIDENT? LETTERMAN
We just had 8yrs of that you ignorant$#%&!@*
yeah, you are full of c**p
Letterman needs to stfu and move to another country
So . So is Letter,man
Trump is ignorant? When was the last time you looked in a mirror? Of course, if I looked like you, I wouldn’t look in the mirror, either. EVER. You not only ARE ignorant & stupid, you definitely LOOK ignorant & stupid.
The beard makes you look a lot older than you really are Dave but you’re still a scumbag
Letterman is the ignorant one!!!!
Why do you think we care. Your opinion means no more than the common citizen
