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.

Never found him that funny… in fact i dont like any late nighters since conan left the air, and even he was kind of irritating depending on the monologue
Americans know who is the true American, all these celebrities are all fools and Americans will in the end will make them pay for not taking the American people’s side
Not funny before u retired or after ass
Letterman isn’t credible looking like a homeless vagrant
Letterman is ridiculous.
Lettermen hasn’t been worth a damn since 80s
Lol its funny how washed up celebrities turn into politicians! ! Go be a good little dbag and be gone like your career.
Just another opinion that does not matter
Says a hadbern talk showhost.
Letterman is a total tool. Always had been.
