spectator thinks of an object, then I tell them to change their mind, cross out their initial thought, write another object, change their mind AGAIN, cross that word out, lastly put an object that means something to them in a special way. In the end, they have 2 crossed out words, 1 uncrossed. I can tell them their exact (or almost exact) train of thought as they thought of the 3 objects. You know...the classic billet p**k with a very...should I say it?...wicked twist. I created the half-billet p**k myself. =)
