The magician has misplaced the phone number of his old highschool girlfriend.

He asks a spectator to help him locate her number by using their psychic abilities.
He gives them a phone directory of the town she lives in.

The spectator is FREE to choose ANY page and stop on ANY phone number and then write it down.

The magician then shows the spectator a photo of his old girlfriend that has been sitting on his stand in a manila envelope the whole time. As he is about to lay the photo back down he notices a slip of folded paper stuck to the back of the photo.

Why it's the phone number of his girlfriend that he was looking for, and guess what?
It MATCHES the number the spectator selected from the phone directory. But that's not all. Sealed in an envelope that has been sitting on the magician's stand the whole time is a prediction he made before the show.

In the envelope is his prediction of the page number the spectator would turn to. The envelope is cut open and handed to the spectator, they then remove the prediction and read it, it MATCHES the page number the spectator turned to in the phone directory. UNBELIEVABLE!!
