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.

Wow! Harsh, but true! (silent chuckle)
More liberals calling people names. Isn’t that what there suppose to be against.
Robert S. Iliff True, harsh, but deserving. Another clown who thinks that all of his years of entertainment fame were meaningful enough to have him render opinions outside his realm of expertise.
I used to respect this man’s opinion
Don’t you have someone to rape Dave
This sounds like the pot calling the kettle black.
David who?
Asshole
Who actually cares what he says
And you are so brilliant.
