On this particular visit, I was most impressed by the show we saw in the medium-sized room, where a random member of the audience (a member of our party was selected for a different part of the show) picked a random name out of a phone book, and Jay Alexander unrolled a scroll to show the exact phone number she had selected. I'm normally not that impressed by these kinds of tricks (where a magician "picks your card," etc) but all I was left with after this performance was the thought that supernatural power was the most likely explanation for what I had seen.
