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 you are the idiot ignorant
Ignorant remarks
Letterman needs a shave and it is affecting his brain.
Ass wipe liberal POS!
Guess father time dine gone senile .
It must be lack of oxygen from having their head so far up their asses and must be confusing Trump with Obama who is still trying to be current president.
He is such an big time idiot!!!!!!
The pot calling the kettle black. Ignorance of Liberal values is a blessing. How anyone can buy into these irrational values boggles the mind. There is bad air in California.
Shut up a hole .
Letterman, You are the Ignorant one.
