This is an incredible chair prediction where:

A woman in the audience is asked to think of an important event in her life, one with which she can associate an important time.
4 chairs on stage are mixed up.
4 Volunteers freely choose to sit in any seat.
The 4 volunteers then freely choose one of 4 numbered envelopes.
Now the gasps begin as you reveal:

The numbers printed in the envelopes match the numbers printed on the backs of the chairs in which the person has chosen to sit.
The card inside of the envelope predicts where the only woman will choose to sit. Finally
The number combination created by both envelopes and chairs is actually the time of a very important event being merely thought-of by the volunteer in the audience. She never wrote anything down before the show and in fact only decided on which event to think of at the moment you stood her up in the audience.
Every choice made by those on stage is a free and fair one. Yet you the performer are in complete control the entire time. There are no stooges, nothing written down before the show, no forces and certainly no ‘special mixing procedures’.

This routine is a closer and for good reason. It takes chair predictions on to an entirely new level.
