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 should be in jail for sexual offenses
Idiot
You have it backwards old man,your friend o-bama is the one you should put your 10 counts of scrap on.Guess you people just won’t believe an honest person for it shows who is the dumb one.
Blah,blah,blah. Just another has been talking nonsense as he did for 33 years.
Really? While he can be crude, he’s laughing all the way to the bank Letterman! If I’m not mistaken, liberals, Hollywood, and not just a few, academia and shown themselves to be crude, rude and pretty damn stupid !!!
