A school teacher injured his back and had to wear a plaster cast around the upper part of his body. It fit under his shirt and was not noticeable. Then, on the first day of the term, still with the cast under his shirt, he found himself assigned to the toughest students in the school.
Walking confidently into the rowdy class- room, he opened the window as wide as possible and then busied himself with paperwork at his desk. When a strong breeze made his tie flap, he took the stapler from his desk and stapled his tie to his chest.
After that incident, he had no discipline problems with any of his students that term!
