Legendary skeptic James Randi has devoted his life to debunking frauds and investigating paranormal and pseudoscientific claims.
In this TED talk James Randi takes a fatal dose of homeopathic sleeping pills onstage, kicking off a searing 18-minute indictment of irrational beliefs. He throws out a challenge to the world’s psychics: Prove what you do is real, and I’ll give you a million dollars! (No takers yet.) http://www.randi.org/site/
