Cats as Can't
I got into a kind of '60s-'70s psychedelic poster mood recently, and this was one of the results, along with Baby, the Rain. It expresses a widely held, but not necessarily entirely valid, belief. The error is usually in reversing the sophism to suggest that critics do so because they can't perform whatever it is they criticize. Of course, nobody we know ever makes such a silly error, right?
