An Unsuccessful Lie
(Originally in Chinese)
The phone rang, and the teacher answered it, saying,
"Hello, may I help you?"
A voice said from the other end, "Is this Mr. Hsieh? I would
like to inform you that Tony cannot come to school today."
The teacher asked, "Who is this, please?"
"This is my father speaking, of course," came the answer.

露出破绽
有一位老师的电话响了，他拿起来问：「喂！请问找谁？」
对方说：「您是不是谢老师？我想告诉您，今天汤尼
没办法上学。」然后那个老师说：「那请问你是谁呀？」
对方回答说：「这个就是我的爸爸讲的！」
