That's a joke!
That would be comparable to an American saying that his father used to remark, "A penny saved is a penny earned." Though everyone knows its from "Poor Richard's Almanac" (by Benjamin Franklin).
Mehr Sein als Schein is the commonplace German expression - attributed to Moltke.
The rule of thumb is: When in doubt, attribute it to Goethe or - if it's salacious - to Oscar Wilde.

That is who I had heard it was attributed to. But when researching on the web I was just getting her attributing it to her dad. LOL. One can’t trust the MSM to do any research.
