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.

Dave Letterman is lunatic!
What does he know? All he ever did was try to be funny but wasn’t! Go away, David! Go back to your mansion and shut up!
Doesn’t he still live with his mommy!
He’s just downright creepy looking.
Letterman, you are ignorant!
He is the President of “We the People”. You are a nobody!!
Every article you’ve shared has been a year old. Are you just recycling old news? Why?
That’s right liberals, just keep calling us names and offer no solutions. I’m looking forward to democrat party presence to nearly disappear in our government during mid terms.
All beard. No brain.
Retiring made you wise? NO!
