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.

Letterman has sucked since the 80s
Who cares what you think! By the way we won you lost! Stick it up your kazoo !
I’m, doesn’t Letterman live in NYC? Leno was the one with the studio in CA.
I hear criticism all the time, but I want facts. What has he done wrong and why do you think so?
Letterman has always been mean-spirited and arrogant.
Another washed up celebrity wanting that attention
Your confused the dictators are finally out of the whitehouse
It seems he is talked nag about Obama not Trump He must be confuse because I don’t see those characteristic in reference to our President. Dilution guy and an idiot
I was never a fan of his. Carson and Leno were my favorites of all time!
Letterman is and always has been a f’n douchebag!
