Richard, as you know, everyone is aware of Bob Carver's Professor's Nightmare. I think it gained notoriety because it became a dealer's item. I saw Carver do many, many things, but my memory didn't latch onto any particular one since I had no intention of "borrowing" it. I wish that I had. At the time, I was content on being a mere spectator. I do recall one effect, however, that I saw him perform several times. It always appeared impromptu although, obviously, it wasn't. It involved some machinations with a dollar bill, the details of which are lost in my memory. The portion that I recall was that the bill increased in size. With a couple of folds, that larger bill also doubled(?) in size. The patter was along the lines of the type of purchases each bill could make. After some more folds, a huge Jumbo bill made its appearance. The bill was tapped lengthwise on the table and as Carver talked about the auto that money could buy, the bill was lowered to reveal a very large toy-sized replica of an automobile! It doesn't sound like much, but the steal was invisible and the load was done on the offbeat. I still don't know where the replica was kept prior to production. This might be old stuff now, in view of all of the popular cup loading and similar moves, but the handling appeared very advanced at the time. It's a pity that it never occurred to me and, obviously, others, to make notes. Bob died at an earlier age than one would have expected and, I guess, none of us, sensed any urgency. Pity.
