A well-known speaker started off his seminar by holding up a $20 bill. In the room of 200, he asked, "Who would like this $20 bill?"

Hands started going up. He said, "I am going to give this $20 to one of you, but first, let me do this." http://www.spam.com
He proceeded to crumple the 20 dollar note up. He then asked, "Who still wants it?" Still the hands were up in the air. http://www.spam.com
"Well," he replied, "what if I do this?" He dropped it on the ground and started to grind it into the floor with his shoe. He picked it up, now crumpled and dirty. http://www.spam.com
