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 senile!!
His beard is just about to cover his face , so
Shut 5he hell up liberal scum
Dolt
idiot$#%&!@*hole
Poor David. U have always been slow
Look who’s talking? The guy who’s messing around with lowly workers on his show. He’s disgusting.
Who cares?
The real ignorance is shown in lettermans mirror, should he choose to look into it
Letterman another liberal snowflake screwup.
