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 is irrelevant..
Who listens to him anyway!
Hater and haters just hate
Oh Letterman, you old has been!
LETTERMAN STICK TO MESSING WITH INTERNS AND KEEP MOUTH SHUT. DIDNT LIKE YOU THEN AND MY OPINION HAS NOT CHANGED. CHECK MESS ON FACE FOR CRABS. YOU NEVER KNOW
The things you rant about, you will never encounter. Transgenders using inappropriate bathrooms, how many times do you think your wife, son or daughter may have this happen to them? You guys want to jump on a bandwagon that you can’t even relate to!
Senile
Go$#%&!@*yourself David
Letterman who cares what you think you has been!!!
Trump 2020
How is he irrelevant Larry he was once a big time funny guy on tv doesn’t that make him smarter than us.
