Unpopular opinion: much of what he said was just total bs. Even in an example from this article, he goes on a tangent about phrases that were not used then and still are not used. "They're not used cars, they're 'previously owned automobiles.'" What? Nobody calls them that, even today, 30 some odd years later.

In my opinion, George Carlin sometimes had some kernel of good observation at the heart of his bits, that he made worse and less correct the more he pontificated on it. And a lot of his observations are the kind of "common sense" folk wisdom that falls apart on closer inspection.
