Mr Henry worked in a middle school. He read a lot and could answer all the questions that his students asked.
One Sunday morning, when he was dressing his little son, Jimmy, suddenly the little boy said, "May I ask you a question, Dad?"
"Of course, you may, "answered Mr Henry.
"Are you sure that you can answer it?"
"Don't you believe me? I'm sure I can. "
"Well." said Jimmy. "are there any holes in your socks? Look at them carefully, or you'll be wrong."
It made Mr Henry pay some attention to Jimmy's question. He took off his socks and looked at them carefully. Then he said, "No, there are no holes in them."
"How can you put your feet into them, then?" Jimmy said with a smile.
Immediately(立刻)Mr Henry didn't know how to answer it. After a while he couldn't help laughing. Finally he understood that his son played a joke on him.
