The scene is a high school assembly where I was speaking. I've asked five students to come on stage with me. One young man is blindfolded and standing in the middle of his four friends. They form a square around the blindfolded guy - one has a $10 bill to give him - if he chooses to come to their corner of the square. The problem is the other three are going to tell him they have the $10 - even though they don't. In fact, they each have something else to give Mr. Blindfold if he comes to their corner. One has a super-soaker squirt gun to baptize him with, one has a full trash can to dump in his arms, and the other has a whipped cream pie to put in his face. This poor young man in the center knows three of his friends will be lying about having the money, one will be telling the truth - but he has to decide, sight unseen, which corner he will go to. They each make their convincing pitch for why what he wants is in their corner. Then, he has to decide which voice he will follow. Right choice - he walks away better off. Wrong choice - uh, messy ending!
