Send you a joke. How to reply to him?

You answer him: it's gone! I missed it (didn't) haha

No means no, which means it's not funny.

Second, instead of ellipsis: no, answer the English teacher with half-baked ellipsis (no).

Gift:

Once I hosted a foreign guest to visit the school and walked to the door of our teacher! In order to show her English level, Liu Hongtao introduced herself: My name is Liu Hongtao! (My name is Liu Hongtao Liuxin) Foreign guests are surprised to be proficient in Chinese: Ah, I thought you were a seven-diamond!

This answer is not good, but I think you are very thoughtful and like to think on the bright side! Taste life, taste life.

good luck .............
