Teacher of Physical Education: Have you ever seen mixed doubles, boys?

Nick: Yes, sir. Quite often. I saw it even last night.

Teacher: Please tell us something about it.

Nick: Oh, sorry, sir. My father always says, ‘Domestic shame should not be published.‘

体育老师：孩子们，你们见过男女混合双打吗？

尼克：见过，老师，经常见。就在昨天夜里我还见过呢？

老师：你给大家讲讲当时的情形吧。

尼克：啊，对不起，老师。我爸爸常说: “家丑不可外扬。”

Funny.
