A woman came to Confucius with a question:
"Tell me, o wise Confucius, what is the difference between polygamy and polyandry?", she asked.
Confucius put on the table five kettles and five teacups.
"Now, woman, fill all the teacups from one kettle. Do you like it?"
"Yes, I do like it," was the answer.
"Fine, now fill one teacup from five kettles and tell me how you like it".
"I like it even more," the woman answered.
"Wretched woman!" cried out Confucius, "now you have gone and destroyed a perfect parable!"
