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.

And who is Letterman to judge???
He went from being funny to a classic liberal piece of c**p. Turned him off years before he got off Late Night.
Immature fool.
Old and irrelevant!
His ideas are as washed up as his late night show.who cares what letterman has to say
I listened to this asshat just this morning on xm radio never again
Ahole!
Another TV asshole
Fool
You were never funny, accept for your looks. You are a hack, and most certainly, insignificant. Just go away, you has been.
