Platitude: an idea (a) that is admitted to be true by everyone, and (b) that is not true.
—H. L. Mencken

Let's have some new cliches.
—Samuel Goldwyn
Any great truth can—and eventually will—be expressed as a cliche—a cliche is a sure and certain way to dilute an idea. For instance, my grandmother used to say, 'The black cat is always the last one off the fence.' I have no idea what she meant, but at one time, it was undoubtedly true.
—Solomon Short
