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. Go To Hell!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Enough
Add a bit of fame and their minds explode to thinking they know everything political.
The media keeps this going!
Another real left loon, who will be laughed at in his golden years.
Idiot!
Letterman is an idiot.
Letterman is a whacky doddle nut
Again. Not helpful.
Dave is gross. Trump 2020!!!!
