谁能给我写一个英语小笑话，加汉语翻译。

One day after school the teacher said to his students, "
Tomorrow morning, if any one of you can answer my first
question, I will permit him or her to go home earlier." The
next day, when the teacher came into the classroom, he
found t he blackboard daubed. He was ver y angry and
asked, "Who did it? Please stand up!" "It's me," said Bob,
"Now, I can go home. Good-bye, Sir."

一天，放学以后，老师对他的学生们说："明天上午，如
果你们当中的任何一个同学能首先回答我的 问题，我就
准许他或她最先回家。"第二天，老师走进教室时发现黑
板被涂得乱七八糟，他非常生气的问："谁涂的？请站起
来！"鲍勃说："先生，是我，现在我可以回家了，再见！"

Teacher: Here are two birds, one is a swallow, the other is sparrow. Now who can tell us which is which?

Student: I cannot point out but I know the answer.

Teacher: Please tell us.

Student: The swallow is beside the sparrow and the sparrow is beside the swallow

老师： 这儿有两只鸟，一只是麻雀。谁
