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 wrote the book on ignorance
Sorry Dave-another sour grapes Dem who thinks he’s smarter than everyone else.
Davey boy you are just upset because you could bot build the number of liberals to follow you.
Who cares what you think?
He is a t**d
You Liberals keep throwing in those scary words hoping we Conservatives are dumb enough to believe they just might be true, well, we’re not!
Oh , and another thing, I never watched you because ….I never liked you !
Letterman you are the stupid Ignorant one. President Trump is trying to put America back together again. After Obama tried to destroy it. And it is Crazy morons like you that can’t even realize that Trump is working for the good of the people. I am sure if you had a brain that you would take it out and play with it.
Who cares what this jerk-wad has to say. His opinion means nothing.
Irrelevant dink.
Letterman, you have gone off the deep end and not just politically. Nuts
