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.

And this is from the all wise david letterman. Takes more than a beard to make you a wise man,Dave.
In a little over 100 days Trump is building a dictatorship! Dave, Roflmao!!
Bye dave
In eight years Obama and his minions had a hell of a crime spree!
I agree,why don’t they shut up, they are just ignorant.
Obama built the dictatorship! He infringed upon our freedom of speech! No one dared talk ill of the Muslims you are called a racist a bigot and Islamicphobia! He even had Loretta Lynch to go out and say that anybody caught would be arrested and several people had been arrested!
So Mr Letterman, you and other Holywood perverse did not mind the Dictatorship of Obama because he shares the same moral compass as you.
This man has never ever been funny. I feel sorry for his son being raised up listening to this rhetoric.
Stupidity
When he trims his beard.. a little bit of wisdom is trimmed also..
