Homeopathy as a Replacement for Goat Balls
In the early 20th century, Dr.JohnBrinkley made a fortune by transplanting goat testicles into men to cure their impotence. 16,000 people received the procedure, thanks to Brinkley's direct marketing campaign, including press agents, newspaper advertising, and a popular radio medical talk show. All these people were suckered in because Brinkley had testimonials. No evidence of efficacy, no explanation of how it worked - just testimonials.
