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 the ignorant one.
You are stupid Lertterman
Go$#%&!@*your intern Dave she likes you nobody else SHITBAG
Actually he is very smart/
Bitter old pervert not at all funny paranoid
Pervert
Dave is a douchebag. Plain and simple. Doesn’t have a clue. Old, senile and ignorant.
He was disgusting, and not funny, only vile.
Letterman looks like a mean bitter Santa. At least he’s hiding that ugly mug with a beard. He needs a positive hobby
U look rediculos!
