Fork Bending

So this is a bizarre photo and story. Went for a meal where they had a magician performing at the tables while you await the bill. So there were a few rather impressive tricks with a pack of cards - though the last one was pretty difficult to understand - then came the fork bending - so he asked me to write my name on the fork, which I dutifully did and then he proceeded to wave the fork in the air for a few seconds - after which the fork was bent out of shape. This happened a couple of times including the handle being completely twisted whilst being held by L and then the final flourish ended up with the fork in this picture. I am still completely bemused by this as we are now in possession of the fork and the writing is definitely the writing I put on it. When I tried to bend it at all, it was totally solid and unbendable! I have no idea how he did this and am still totally impressed by whatever Yuri Geller sleight of hand was going on here!
