Une anecdote sympa trouvée sur le café vert, écrite par Nick Pudar:
We went to visit good friends for some joint-family birthdays. We visit these friends three or four times a year at their home. On this particualr occassion, they had invited some other some other friends, so there was a full house. As dinner was winding down, the hostess asked me if I could do some magic for the group, as many of the visitors had not seen me perform before. I had not brought anything with me, so I asked if they had a deck of cards I could borrow. She went off to find a deck, and I was dreading the worn and beer stained, sticky cards which were likley to be provided. Fortunately, the card case looked very new. When I opened it and spread the cards, I was shocked to see that they were in Aronson Stack order!
My mind flashed back to the last time I did magic at their house, and I remembered that it was probably two years ago. I must have left the deck in Aronson Stack order, and they must not have used the cards in that entire time!
I immediately launched into a few killer memdeck routines, and floored them all. On the way home, my wife said, "Wow, you're really getting good at setting up your stack quickly. I can't believe how fast you did that."
I suppose I'll never have that happen again!
