 In 1973, Geller appeared on "The Tonight Show", and this appearance is recounted in the "Nova" documentary "Secrets of the Psychics".In the documentary, Randi says that Carson "had been a magician himself and was skeptical" of Geller's claimed paranormal powers, so before the date of taping, Randi was asked "to help prevent any trickery".Per Randi's advice, the show prepared its own props without informing Geller, and did not let Geller or his staff "anywhere near them".
