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.

LOL, globalization idiot !
Who gives a$#%&!@*what Letterman thinks
Shitty beard, shitty libtard, Obama was the would-be dictator
And That’s just the “short list”!
He and killers need convictions
Letterman doesn’t even know where he is half the time.
Never liked, never watched, just another retarded elitist
Dave, Canada is calling You!
Make sure you get that nasty beard disinfected before you go though…
Ahole
Smh
