Having served his time with the Marine Corps, a man became a high-school teacher and before school started he injured his back. He was required to wear a plaster cast around the upper part of his body. Fortunately, the cast fit under his shirt and wasn't even noticeable. On the first day of class, he found himself assigned to the toughest and most delinquent students in the school. Walking confidently into the rowdy classroom, he opened the window wide and sat down at his desk. When a strong breeze made his tie flap, he took a stapler and stapled the tie to his chest.
He had no trouble with discipline that year...
