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.

Yikes! What happened to you!?? You look like you ‘ve been dragged through a knothole backwards!! And speaking of ignorant, you are one of the biggest ignoram uses I ever saw!
I remember when you were funny and not a miserable,angry old man. I feel sorry for you
He would not a Dictatorship if it bit him on the head of his peter.
Ah David, if only we cared….
I haven’t heard one educated, and thoughtful criticism of President Trump. They always call names, they dont debate his policies. Any President is open to criticism, but all I hear is personal attacks
He needs to go back in the woods with Hillary!
What would anyone expect of Letterman as he was a liberal, democrat political hack with NO original thoughts. A real phony!
Tell Rip Van Winkle to go back to sleep!
Who cares… he must be suffering from dementia…poor thing…
He is so STUPID. Never like his show. Not a funny guy
