You are at a party and announce that you have a friend who is such a great psychic that he can tell what card someone picked out of a deck via the telephone.

You then get a pack of cards and ask for the group to select someone to pick a card from the deck. At this point there are two variations: 1) If you know how, you can force a card on the person or 2) you can spread the cards face up and let the person pick one. Then you go to the telephone and call your psychic friend. You say "Is (name) there?" followed by "(name) this is (your name)" and finally "(name) will you tell (selectee's name) what his/her card is?"

The friend then correctly identifies the card.
