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 ignorant!
Famous people automatically think they are smart! I got news for you jerk!
I’ll tell you what Dave ,I recall Ellen Degeneros say she would never make fun of another person to get a laugh and she’s a hell of a better comic than you could ever be! just because you got away with your nastiness does not make you smarter than anyone else! You are the ignorant one Dave! you haven’t a clue to what wisdom is! Stay behind your beard and out of sight, you are repulsive
Shut your pue hole letterman
Letterman is stupid but he is getting worse
Letterman, thorough disgusting
Erma, that was so funny
Letterman shows how really stupid he is
He’s a flaming idiotic moron!!!
Just another entertainment monkey looking for attention!
