英語幽默:兩只鳥

Teacher: Here are two birds, one is a swallow, the other is sparrow. Now who can tell us which is which?
老師： 這兒有兩只鳥，一只是麻雀。誰能指出哪只是燕子，哪只是麻雀嗎？
Student: I cannot point out but I know the answer.
學生：我指不出，但我知道答案。
Teacher: Please tell us.
老師：請說說看。
Student: The swallow is beside the sparrow and the sparrow is beside the swallow.
學生：燕子旁邊的就是麻雀，麻雀旁邊的就是燕子。
