English Original
The teacher noticed that Johnny had been daydreaming for a long time. She decided to get his attention.
"Johnny," she said, "If the world is 25,000 miles around and eggs are sixty cents a dozen, how old am I?"
"Thirty-four," Johnny answered unhesitatingly.
The teacher replied, "Well, that's not far from my actual age. Tell me... how did you guess?"
"Oh, there's nothing to it," Johnny said. "My big sister is seventeen and she's only half-crazy."

老师注意到约翰尼已经走神很久了。她决定吸引他的注意力。
"约翰尼，"她说，"如果地球周长是25,000英里，鸡蛋是六十美分一打，那我多大了？"
"三十四，"约翰尼迅速地回答。
老师回应道："嗯，这和我的实际年龄相差不远。告诉我...你是怎么猜到的？"
"哦，这没什么，"约翰尼说。"我姐姐十七岁，她才半疯。"
