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.

He’s a comedian, an evil person and needs to stay away! Doesn’t he k n ow he’s a has-been and nobody listens to him?
I have the n a me of a first rate retirement home for David!!
Amen
Is this classless old man still trying to be on air??
Look in a mirror p***k ! There’s your ignorant loser !
Not worthy of a coment!
Go back to sleep Letterman!
He looks like a mess!
Jackass!!
Looks like a grumpy old man who forgot to shave or think any more.
