Some semi-random browsing led me to this video of James Randi debunking Uri Geller’s claims of paranormal powers, with some other Tonight Show appearances. We definitely need more interviewers like Johnny Carson. He set up a controlled test for Geller’s "powers" and was rewarded with a refusal to perform.
I have to wonder why some magicians need to claim that they have real paranormal powers. Isn’t it far more impressive to be able to fake it, the way Randi and Derren Brown do?
