Brumoli's Mental Magic Swindler Test (MMST) 2000

A spectator thinks of any day significant to him. He looks up this day in a beautiful multi-colored calendar book which has a different playing card next to each day of the year with a green or blue border around it The performer has his back turned the entire time. The performer instructs the spectator to call out the colors of the borders of the 7 cards in the column in which his card resides. However, when the spectator reaches his card, he lies and calls out the wrong color! Nevertheless, the performer knows the identity of the card!
