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.

I guess no one realized Letterman is bi polar and a semi paranoid schizoid and half of what he has to say is delusional
Letterman calling anyone ignorant is a real laugh.
Letterman is just an angry old Liberal Prog!
Who cares what that piece of trash thinks or says
It looks like he went off the deep deep end- kinda reminds me of Tom Hanks stuck on the island
These ppl just need to go away.
Late night talk shows ended when Johnny Carson retired!!!
I thought Letterman retired his silliness
Liberal t**d
Hey! Letterman! You did your entertainment gig and got paid for it! Did you somehow forget your place? You were entertainment, that’s all. Now that you’re NOT in that business anymore, SHUT UP! Nobody cares what the dancing monkey does after a show. No one cares what a clown does at home. And no one cares what you think.
