There is this school in the middle of this country somewhere where every Thursday the teacher would ask the children a question. If anyone ever got it right they would not have to come to class on Monday.

One time she asked them "How many gains of sand are on the beach?"
When they came in on Friday nobody had the answer.
The next Thursday she asked "How many stars are there?"
When they came in on Friday nobody had the answer.
One kid had enough of this and was determined to get Monday off.
That night he went home and found two tennis balls and painted them.
Then next day when the teacher gets ready to ask the question, he throughs the balls across the room.
The teacher then askes
"Who's the joker with the black balls?"
The kid jumps up and states
"Eddie Murphy! See ya Tuesday!"
