"Play Hookey" joke
It was a bright spring morning and 4 high school students decided to play hookey. They didn't arrive at school until after lunch and told the teacher as their excuse that their car had a flat tire. (Remember the days when you had to walk and take the bus? These kids have their own cars today!) Anyway, back to the story... To their relief, the teacher just smiled and said, "You boys missed a little quiz this morning. Please take seats apart from one another and get out your pencils and paper."
When the boys were seated at their desks (far apart), the teacher said, "OK, now each of you is to write an essay on WHICH tire was flat and how you fixed it."
