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.

Dumb ass
He looks like a hermit.
Another slime bag
Nice look David!! Like a Santa Claus reject!!
A white Imam…real$#%&!@*
B******t peddler to looser and liar
OH,!” This Puke
Hey Dave stay retired and put your head back in your$#%&!@*where it belongs
Nobody cares what this dumb bastard thinks or says.
Is that Santa?
