Thank you, Johnny
He'll be missed. He set the standard against whom all other talk show hosts are measured. But on the other hand, he didn't invent the wheel, so let's not get carried away here. He drew heavily on those who came before him. He got many of his reaction takes from Groucho Marx & Jack Benny.
I remember during the successor flap between Leno & Letterman, he stayed out of the fray. But to his credit, his producers helped Letterman craft a deal with CBS that enabled him to leave NBC which had treated Dave shoddily, to launch a new show on CBS. Even lately, he would occasionally send Dave a joke that was used.
RIP
