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.

Poor old guy….
Deal with it Santa!
Sorry never was a fan of your show and watched Leno. Your opinion is yours and not the peoples.
And you are ugly so
This coming from the buck tooth Wiesel gee that’s why he has built the Finnic all wmpire he is
He was that good
Looks like he has aged and the bearded look does not suit him.
U aren’t funny anymore
Your the ignorant one!
Letterman you are stupid
