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.

Muslims got your brain too I see
Is that why he run around in a multi million dollar luxury jet.
How many Trump towers & skyscrapers you built donkey brain.
Pretty obvious who is stupid here. You are.
What a way to go out David. Sad. Sad sad.
Sigh
He defeated old Letterman and old LET is still bellyaching about it. Get over that little tiny ego you have you pathetic creature..
Crawl vack under your rock…no one missed you!!
All part of the marxist playbook.

Aint never liked him
Time for pos to die shoulda been dead
Mr letterman

Enjoy life on an Indiana funny farm
