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.

Dave has always been a clearly bitter and troubled man…was glad to see him go!

This guy is a fucktard and always has been
Your wrong your the ignorant one
Who cares what this has been thinks?
Who shivs a git!?!
Shut up Letterman. Do you have family that could get involved with the amounts of drugs coming into America? Go comb your beard and think about how you were stalked.
Liberal jerk , full of himself and has shown he’s not at all in tune with half the nation’s voters.
Who gives a rats$#%&!@*what Letterman thinks.
Do you have a fence around your home?
