Behind every man

"Behind every man who's a failure there's a woman too!"

Someone famous gave that quote as well. I forget who.

That was the caption of a cartoon in Playboy, March 1967 by John Ruge (untraced).
As usual there's a great woman behind every idiot. John Lennon in 1979.
We in the industry know that behind every successful screenwriter stands a woman. And behind her stands his wife. Groucho Marks quoted in 1977.
