One Friday afternoon, a first grade teacher said that she was going to ask the class a question and whoever get it right would get to take Monday off.
The class got very excited and listened very closely. "Who went..." she began her question but was interupted because someone rolled black marbles across the floor to her. "Alright!" she said. "Who's the wise ass with the black balls?"
"Martin Luther King Jr." Little Johnny shouted. "See ya on Tuesday!"
