One day, the teacher walked into her classroom and announced to the class that on each Friday, she would ask a question to the class and anyone who answers correctly doesn't have to go to school the following Monday.

On the first Friday, the teacher asked,

"How many grains of sand are in the beach?"

Needless to say, no one could answer.

The following Friday, the teacher asked the class,

"How many stars are in the sky?" and again no one could answer.

Frustrated, little Johnny decided that the next Friday, he would somehow answer the question and get a 3 day weekend. So Thursday night, Johnny took two ping-pong balls and painted them black.

Friday, he brought them to school in a paper bag. At the end of the day, just when the teacher said,

"Here's this week's question..."

Johnny dumped the bag onto the floor, sending the ping-pong balls rolling to the front of the room. Naturally, young kids find any disruption of class amusing, the entire class started laughing.

The teacher said,

"Okay, who's the comedian with the black balls?"

Immediately, Lil' Johnny stood up and answered,

"Eddie Murphy! See ya on Tuesday!"
