Actually, although I don't know if it was from him or not, it does indeed sound like something he would say, as he believed very much that you could explain the universe in very simple, elegant terms which anyone, even a child, could understand. He intensely disliked quantum mechanics partly because of the mathematical "noise" which made it so difficult to express in simple terms (Schrodinger, whose wave mechanics turned out be merely a simpler form of matrix mechanics, felt much the same way).
It's often forgotten today that Einstein spent as much of his time trying to explain relativity and basic physics to the general public as he did on physics itself. The Evolution of Physics, which he co-wrote with Leopold Infeld, remains a classic text.
That's a great book, I have my copy near my bedside, 5th printing, Simon and Schuster, 1938.
I should re-read his "Out of my Later Years", Philosophical Library, New York, 1950.
