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.

Time to fade off into the sunset Dave. When have you ever been qualified to critique the presidency? Just another unimportant arrogant Hollywood hack…
Who is the ignorant one you idiot??? Not trump so that leaves u.
Letterman who?
You’re a liberal, about 10 notches below a roach. You just disqualified yourself from passing judgment on my President Trump. Thank you!
You’re an ugly old man, Jackass stfu.
Since when did you get so smart
I remember him when he wasn’t a bitter old man.
Tell me , Dave, just what has Trump done to build a dictatorship ?
Mr Trump is ‘most intelligent men people just jelouse becose is the best…
Mr Trump is the most intelligent men …
