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.

Go build something, Dave, without writers, dumbass
You old$#%&!@*wad
OMG, look who’s talking
Just go away !
This is why he’ll never measure up to…….”Heeeeres Johnny!”
You are ignorant Letterman. Trump is for the people only.
This guy can’t do anything but make fun of other people and call it comedy, and he’s calling Trump ignorant. He is the joke.
Shut the$#%&!@*up u dtupidjerkoff
He has gone senile a very bitter man.
First indications of dementia. Bet he drops out of site within 24 months as his mind goes completely.
