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.

David letterman has low character! Thinks he is smart but he is not!
U are one of it letterman.
ASS!
And you are not ignorant: is that the premise? Who set you up as not ignorant?
I used to watch your show. I won’t do it again. If I did then I would be as bad as you.
Go away before you embarrass yourself.
And what are you ?
A stupid clown
Frankly, I’m not interested in his opinion on ANYTHING! Never watched him, ever will.
So glad he’s retired. Trump is tryouts NCG to tear down the Lib establishment making idiots of millions.
If Trump wasn’t president, letterman, Colbert, Mahr etal would be kissing his$#%&!@*on Rodeo Dr.
Another Trump basher
You entertainers are just plain jealous of Mr Trump! He is successful and you ain’t!
