The video explores the origin of the phrase 'snake oil' and its association with deception. It traces back to the 1800s when Chinese immigrants used snake oil for joint pain relief. Clark Stanley capitalized on this, marketing his own snake oil liniment with exaggerated claims. His public spectacles drew both admiration and skepticism.
