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 your the ignorant$#%&!@*
Old news. Who cares
Give me one good reason to listen to anything this guy says.
I watched your show on TV for years, and I really liked you, but I cannot say that today with the attitude you have now
If you hate the righteousness of almighty god you’ll love Letterman
STUPID, UGLY LEFTIST FUCKER
who paid Santa Claus to talk trash about Pres Trump? lololol
He’s looking old and tired and confused.
He earns from a business not just talk !!
Letterman is a liberal pogue who is a stupid as Hillary Clinton and Bill is a person of moral uprightedness
