Several hands went up, but the lecturer said:
"Before handing it over, there’s something I must do."
He furiously crushed it, and asked again:......
"Who still wants this bill?"
The hands continued raised.
"And what if I do this?"
He threw it against the wall, letting it fall to the floor, kicked it, stamped in it and again held up the bill - all dirty and crumpled. He repeated the question, and the hands continued to be held high.
"You mustn’t ever forget this scene - said the lecturer. - No matter what I do with this money, it’ll still be a 20 dollar bill. Many times in our lives, we are crushed, stamped on, kicked, maltreated, offended; however, in spite of this, we are still worth the same."
