The Yogi's Prediction

Performer shows an envelope and a blank card. He says that though he is not a fortune teller, he can often tell how the human mind will think before it does. For instance, he will write a prediction on the card, place it in the envelope, seal the envelope, and have a spectator initial it so that there will be no exchange of envelopes.

Magician then asks one spectator to give him a number between one and one hundred thousand, another to name a city, another to call out a color, and still another to name any day of the week. He tears open the envelope, removes the card - and to everyone's amazement, there written on the card are the number, the city, the color, and the day which spectators called out.
