I often watch this as it's lovely car-crash viewing.
Uri Geller is checkmated miserably on the Johnny Carson TONIGHT show. Carson had been in touch with sceptic James Randi before the interview took place and Randi advised Carson (who had also been a magician himself) to stop Geller having access to any of the props being used and other tips.
Watch as an increasingly irritated Geller's powers inexplicably desert him. He even gets snarky with poor old fellow guest Ricardo Montanban (KHAAAAAAANNN!!!).
"This scares me" says Geller at the start of the interview.... 2 mins, 15 seconds in.....
Despite this interview, Geller is, of course, still active in his chosen profession to this day.
