In 1973, Carson had a legendary run-in with popular psychic Uri Geller when he invited Geller to appear on his show. Carson, an experienced stage magician, wanted a neutral demonstration of Geller's alleged abilities, so, at the advice of his friend and fellow magician James Randi, he gave Geller several spoons out of his desk drawer and asked him to bend them with his psychic powers. Geller proved unable, and his appearance on The Tonight Show has since been regarded as the beginning of Geller's fall from glory.

James Randi, psychic debunker, speaks at Google on the supernatural, psychic powers, homeopathy and dowsing.
