"Clark Stanley reached into a sack, plucked out a snake, slit it open and plunged it into boiling water. When the fat rose to the top, he skimmed it off and used it on the spot to create 'Stanley's Snake Oil,' a liniment that was immediately snapped up by the throng that had gathered to watch the spectacle. Little wonder. After all, Stanley had proclaimed that the liniment would cure rheumatism, neuralgia, sciatica, lumbago, sore throat, frostbite and even toothache."
