Outside New york University building a shoe-shine boy met Albert Einstein, the famous scientist, and asked, "Shoe-shine sir?" Einstein smiled and shook his head, "No sorry, but if you wash your face, I will give you a quarter doller." The boy briskly ran off to a nearby tap. He washed his face and came back. "Well, that is better," said the shabby haired scientist and gave the boy a quarter doller. "What will you do with this money?" he asked.
The boy looked at Einstein and said, "I would like to give it back it to you, if you promise to get yourself a hair-cut."
