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.

No fucking way but you keep swallowing
Yeah that’s it
What the hell has he done lol
And you need a shave because looking at you is not very pleasant!
President Trump loves America and is working for us.
That’s not true
Why do these washed up celebs think they know more than Trump
DEATH TO LIBERALISM commies and socialists!
Poor, poor man. Got pushed out of his night job and so bitter he decides to trash the one man trying to help this country. So bitter. Clean around your own front door first instead of lying about someone smarter than you.
Trump is awesome. You people in glass houses should be very careful when you throw stones. Americans may start breaking your glass house down and knock you off your pedestal while there at it.
