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 think David is the ignorant one!!!!
Letterman was always a mean humorless jerk and is/was a curmudgeon before his time
Letterman is a joke
never did like his show,don’t like him any better now,
David Letterman has always been an$#%&!@* Sure talks a lot of c**p for only being a talk show host. Sit down and shut up Dave.
I have NEVER liked Letterman.
Never thought he was funny, just pretentious… Stopped watching him long before he RETIRED…… NO RELEVANCY…. JUST ANOTHER BACKSTABBER!!!! Trump was good enough to bea paid guest, now he turns on him…. What a hypocrite
Idiot simply irrelevant.
Has been imbecile
This coming from a late night comedian who open his mouth to get laughs from his stall jokes.
