The master, to impress on his pupils the need of thinking before speaking, told them to count fifty before saying anything important, and one hundred if it was very important. The next day he was speaking, standing with his back to the fire, when he noticed several lips moving rapidly. Suddenly the whole class shouted: Ninety-eight, ninety-nine, a hundred. Your coat is on fire, sir!

老師為了讓學生記住先思考后發言，告訴他們在說出重要事情之前先數到50，如果是特別重要的事情，要先數到100。 第二天，當老師背靠著火爐講課時，發現好幾個學生的嘴唇在很快地不停地動。突然，全班學生一起喊道：“九十八，九十九，一百。老師，您的大衣著火了！”
