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.

You are also ignorant just sitting spouting hate and division in our country we really have to support our president at this ominous time we don’t need a lot of noise that’s not needed
He went from telling jokes to being one.
dave has grown over the years to become a liberal, angry, old, self hating jew. He was never funny that’s why when Johnny Carson retired Leno took the job.
Who’s ignorant Dave????? Take a good look at your dirty self…
What the F*** happened to him ???? ‘ Drinking from that poisonous celebrity water ???? What a tremendous disappointment !!!!!
None so blind as those who will not see! The Dems are trying to build the dictatorship!
Senial!!!
Santa? No, I see David Ogden Stiers….
Talk about ignorance. He is clueless.
Letterman needs to go to the nursing home, He needs round the clock care. He has clearly lost his mind.
