English Original
A teacher friend injured his back and had to wear an upper-body plaster cast.
At the start of the new term, with the cast still concealed under his shirt, he was assigned the school's most undisciplined class. He stepped confidently into the rowdy classroom and opened the window wide. A sudden gust of wind made his tie flap. To secure it, he picked up a blackboard eraser and hammered a large tack right through his tie and into his chest.
He had no discipline problems for the rest of the term.

我的一位教师朋友背部受伤，不得不穿上了上半身的石膏护具。
新学期伊始，石膏仍藏在他的衬衫下，他被指派去教全校最不守纪律的班级。他自信地走进喧闹的教室，将窗户开到最大。一阵强风突然吹起，让他的领带飘动起来。为了固定领带，他拿起一块黑板擦，将一枚大图钉径直透过领带，砸进了自己的胸膛。
那学期余下的时间里，他的课堂再未出现纪律问题。
