Answer

In the old days, there were two pupils in China, A and B, try to cheat in their exam. Since there were having exam in two different places, they decided to use pigeon to send their answers to each other.
After the exam, the Emperor was very satisfied with the answers they gave in the exam.

However, after a more detailed checking of answer, the Emperor was furious with B's answer.
You know why?
Since B was told by A that he should copy every answer that he send to B, B copied everything, including a reminder note in the first page: "There are 2 more answers at the back"...

The lesson behind this (modified) story which was told by my lecturer is: Don't copy everything exactly the same from your friend's answer :)
