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.

I share your comments exactly – NEVER saw anything funny about him. He couldn’t hold a candle to Johnny Carson or Jay Leno!
Shut up nobody likes you why do you think your not on tv anymore alchy bum
Bitter old loser. Poor dave never got over Jay Leno getting the Tonight show from Johnny Carson. Drove him mad really. Look at his picture, he’s practically a unibomber !
Letterman , trump is a billionaire , are you a billionaire , I didn’t think so, and your calling him ignorant , look in mirror , 3 class comedian .
Trump is a lot smarter the letterman !
Never liked Letterman, never will.
Who cares what your opinion is ole Dave
