The teacher in Little Johnny's class decided to make a deal with her class. Every Friday at the end of the day, she'll ask them a question and whoever answers it can get a three-day weekend. Well for a couple of weeks, The teacher asked outrageous questions like "How many stars are there in the sky?" or "how many grains of sand are there on the beach?" Of course they're impossible.
But Johnny got desperate to get that three-day weekend. So, on Thursday night, he took two ping-pong balls and colored them black and put them in a paper bag.
Next day when the time came for the question,soon as the teacher said, "It's time for the question of the week!"
He emptied the bag and the ping pong balls rolled to the front of the room. Since they are third graders, they snickered and all, then the teacher said, "Okay, who's the comedian with the black balls??"
Little Johnny sprange up and yell, "Bill Cosby! See you on Tuesday!"
