One day，the teacher walked into her classroom and announced to the class that on each Friday，she will ask a question of the class and anyone who answers correctly doesn't have to go to school the following Monday.

老师走进教室，向同学们宣布说，以后每星期五她都会问大家一个问题，谁答对了下星期一就不用上课。

One the first Friday，the teacher asked，"how many grains of sand are there on the beach?”Needless¹ to say，no one could answer.The following Friday, the teacher asks the class，“How many stars are there in the sky?”and no one could answer.

第一个星期五，老师问:“沙滩上有多少粒沙子?”不用说，没人答得上来。第二个星期五，老师问:‘天上有多少颗星星?”还是没人答得上来。

Frustrated，little Johnny decided² that the next Friday，he would somehow answer the question and get a three-day weekend. So on Thursday night, Johnny took two ping一gong balls and painted them black. The next day, he brought them to school in a paper bag. At the end of the day，just when the teacher said，"here’s this weekend’s question，"Johnny emptied the bag to floor，sending the ping一pong balls rolling to the front of the room.

小强尼沮丧极了，他决定下星期五设法回答出老师的问题，过一次连续三天的周末。星期四晚上，强尼找了两个乒乓球，并把它们染成黑色。第二天，他把乒乓球装在了一个纸袋里带到了学校。这一天的课快结束的时候，老师说:“这一星期的问题是—”话还没说完，强尼就把乒乓球从纸袋里倒出来，把它们滚向讲台。

Because they were young kids who find any disruption³ of class amusingthe entire class started laughing.The teacher said，"OK，who's the comedian⁴ with the black balls?"Immediately，little Johnny stood up and said，"Johnny Henry，see you on Tuesday”

小孩子嘛，只要能打断老师的讲课，他们都会觉得好玩，于是全班哄堂大笑。老师问:“这些黑球是哪个捣蛋鬼的?”小强尼立刻站起来说:“是强尼·亨尼的，我答出来了，下星期二见!”
