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.

Yuck yuck yuck and yuck
He meant to say dismantling a dictatorship, its hard to hear through that beard..
Senile old codger giving political advise.
Go back to your rock in la la land.
Trump isn’t ignorant!
Libtardism
POS
What the heck happened to Letterman? He looks like father time.
He’s a jack ass
F**k OFF Dave
