For those old enough to remember Johnny Carson, that was appointment viewing.
I cannot even begin the number of lost sleep hours waiting for Johnny to come on at 11:30 each night.
Total class act. No matter who was in the White House, you never could figure out if he was a Republican or a Democrat. He made jokes about all the presidents but his comedy was never mean spirited.
Jay Leno, Carson's replacement, was mostly not bad but he wasn't nearly as great as Carson.
It all went downhill from there.
I haven't watched late night shows in years, including SNL, which I used to love.
They are mostly full of hate these days and not entertaining at all.
Leno wasn’t as good as Carson but he did at least try to be funny and entertaining. He at least, was a professional. He did not come across as bitter, angry, preachy, intolerant, ie as a Leftist. All those after him did/do.
