Little Johnny was in class when his teacher told the class that she would be introducing something new. Every Friday she would ask them a question and the quickest student to get it right would get the next Monday off school.
The first Friday she asks them ‘how many blades of grass are there in the field?’ Of course no one puts their hand up.
The second Friday she asks them ‘how many stars are there in the sky?’ Again no one puts their hand up.
Little Johnny, determined to get Monday off decides to prepare for next Friday. He collects a bag of ping-pong balls and paints them black then takes them in for Friday’s question.
That Friday the teacher finishes the last lesson and is about to ask the question when 20 black balls fly around the classroom. Crossly she says ‘who’s the comedian with the black balls?’ Little Johnny replies ‘Bill Cosby, see you on Tuesday!’
