In this 2007 TED talk, magician and renowned skeptic James Randi exposes the bunk of homeopathy and the deceptive activities of mediums and psychics. In his own unique and straightforward way, Randi demonstrates how easily people make assumptions and how snake oil salesmen take advantage of gullible people who believe that psychics can talk to the dead. He also shows how incredibly stupid homeopathy is as he overdoses on some homeopathic sleeping pills. This is one entertaining presentation and if you ever wanted to see James Randi posing as a Grecian warrior fighting on the side of Agamemnon, then you are in for a pleasant surprise.

Enjoy!
