So, kinda like being at a ho****e, eh? Hehe... Stupid forum software.
I used to do a fun card trick with a friend of mine that would get the unsuspecting. I would have someone pull a card out of a deck, make a phone call to Mr. Wizard and, when I put them on the phone, Mr. Wizard would tell them what card they had pulled. Neat trick actually.
How we would do it is like this:
Whenever I called my friend on the phone I'd ask for Mr. Wizard and he would immediately start going through the suits (Clubs, Diamonds, Hearts, Spades...) and, when he said the correct suit, I would say "Yes, may I talk with him please?" then he would start going through all of the cards in a suit (A, 2, 3, etc.) until I heard the right one at which time I would say "Hi Mr. Wizard, I've got someone here who would like you to tell him what card he is holding." Then I would hand the phone to the guy holding the card and my friend would intone "You are holding the [insert the full answer here]." before hanging up. Hmm... We haven't done this trick in at least a dozen years, might be fun to remind him of it!
