James Randi is still the world’s ultimate skeptic; a magician who has spent his career debunking supernatural and psychic claims all over the world. He’s appeared on the Tonight Show, where he exposed faith healer Peter Popoff, he’s worked with Penn & Teller on their skeptic-based documentary show Bullshit!, and even founded the James Randi Educational Fund, which hosts a challenge that will award anyone who can demonstrate supernatural ability under scientific criteria $1 million (no one has won the award).

Back in 1993, Randi helped to produce an hour-long special called Secrets of the Psychics for PBS documentary show Nova. The documentary explores his relationship with psychic claims as a magician, his own methods for debunking fraud, as well as his famous battles with Uri Geller and Peter Popoff. Take an hour out of your lazy Sunday to watch reason prevail against fraud in the video embedded above.
