The teacher asks a question

Little Johnny is in a class where every Friday the teacher asks a question and if you get it right you don’t have to go to school on Monday.

The first Friday the question was, “How many gallons of water is there in the whole world.”

No one knew so they all had to go to school on Monday.

Next Friday, the question was, “How many grains of sand is there in the whole world.”

No one knew so they had to go to school on Monday.

By this time Little Johnny is getting mad because he doesn’t want to go to school on Monday.

So he paints two ping-pong balls black and the next Friday right before the teacher asked the question he rolled the ping-pong balls up to her.

She asked, “Alright, who’s the comedian with the black balls?”

Johnny said, “Eddie Murphy, see you Tuesday.”
