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.

Funny, I always thought Dave was pompous and ignorant
Sick leftist drivel.
He’s the idiot
Not near as ignorant as Letterman!
Dave, I liked you. Don’t mess up your legacy now. STFU about politics!
David Letterman, just a bitter old man. He never got over losing the Tonight Show to Leno. He was always passed over Bc nobody could stand him. He hardly ever did standup outside his show bc he wasn’t any good at it.
Blah blah blah. ..I’m so tired of Hollywood
More f**e news from a top f**e news site.
He’s always been a strange duck
These clowns think they are so stinking smart. These people can’t even run their own lives.
