Mr. Scott worked in a middle school. He read a lot. He taught well and could answer all the questions his students asked. And they liked him very much. One Sunday morning, when he was dressing his son, Jimmy, the boy suddenly asked, “May I ask you a question, Dad?” “Of course you can,” answered Mr. Scott. “Are you sure that you can answer it?” “Certainly.” “Well,” said Jimmy, “Are there any holes in your socks?” “Holes?” Mr. Scott said in surprise. “It’s impossible.” “Look at them carefully, or you’ll be wrong!” Mr. Scott took off his socks and looked at them carefully but didn’t find anything wrong.
　　“No, there’s no hole in them,” said Mr. Scott. “I bought them only last week.” “How can you put your feet into them, then?” Little Jimmy said with a smile. At first Mr. Scott didn’t know what to say. After a while he began to laugh with a red face.
