A joke about students being punished.

A man went to buy a parrot and saw a sign in front of it: This parrot can speak two languages, 200 yuan.

In front of another parrot, it was written: This parrot can speak four languages, and the price is 400 yuan.

Which one should I buy? Both are shiny, very flexible and lovely. The man turned and couldn't make up his mind.

Suddenly I found a parrot with a tooth missing. Its coat color is dim and messy, and its price is 800 yuan.

The man quickly called the boss: Can this parrot speak eight languages?

The shopkeeper said, no.

This person is strange: then why is it so old, so ugly and so incompetent that it is worth this number?

The shopkeeper replied: because the other two parrots call this parrot boss.

What I answered before was adopted, and now I think of you.

Because this joke really impressed me. . . I hope I can help you.
