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.

A young fool who was always an also ran on late night, remains a fool in his old age.
Letterman is a liberal idiot!
What is he now ? An imam or a car bomber, that ridiculous mop he’s got hanging on his face is a joke. Go away letterman, nobody cares what your liberal commie$#%&!@*thinks. Get off my computer.
Asshole Loser
Dave go lay down somewhere before you hurt yourself… Dumbass
Letterman, having worked in the late night hours is certainly not an expert on anything other than darkness. The Top 10 Worst things a human being can do to another? Call your fellow citizen “Ignorant” is #1 on this list!
