I interviewed George Carlin many years ago when I was still with CBS News. We hit it off. He was both funny and very smart. Very liberal, too, but that never came out in our interview. One of his points was that we humans had made a mess of things and he wanted the world as we know it to end. He wanted a big meteor to destroy the planet. And for good measure he wanted it to sail right through the hole in the ozone layer. But he wanted Los Angeles, where he lived, to be the last to go. Why? Because, he told me, he wanted to watch the destruction, one city at a time, on CNN.
