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.

Hollywood go away you are stupid without your scripts that tell you what to say!!
David Letterman you are one dumb son of a$#%&!@* Obama is the one that wants a dictatorship along with Pelosi. What do you think Obama care is. Once the government takes over healthcare we lose our freedom. You dumb ass
Yeah just what the world needs. Another of the elite telling us we are dumb for picking Trump. F U

Creepy
Trying to make a comeback by joining the show business traitors? Infamous is better than no famous?
No one really cares what you think$#%&!@*
You are an idiot.
While Letterman sat in a chair and made jokes with celebrities Trump built five star hotels and casinos and compounds all over the world, yet idiot sits on his rumph still and calls the creator ignorant,
Go away you idiot, Carson was right about you.
