It was the first day of summer school. As the principal made his rounds, he heard a terrible commotion coming from one of the classrooms. He rushed in and spotted one boy, taller than the others, who seemed to be making the most noise. He seized the lad, dragged him to the hall, and told him to wait there until he was excused. Returning to the classroom, the principal restored order and lectured the class for half an hour about the importance of good behavior. "Now," he said, "are there any questions?"

One girl timidly raised her hand then stood up. "Please sir," she asked, "May we have our teacher back?"
