When it comes to tautology, it goes without saying that ‘It goes without saying’ is the sentence by which all unnecessary, redundant and superfluous verbiage must be measured.

Time and time again I see that sentence written somewhere, or hear it spoken, and it goes without saying that it drives me nuts. Of course, it goes without saying that I never use it myself.

Why did someone ever make up that stupid phrase? It goes without saying that they must have been a complete moron.
