When did Ceng Xiaoxian in ipartment say "Oh, it's a joke"?

Ceng Xiaoxian told a joke. The joke is like this: a monkey sees a card in a tree, and the monkey climbs up the tree to get it. As a result, suddenly a flash of lightning hit it, and the monkey said sadly; It turned out to be an IP card!

This is a joke. Ceng Xiaoxian thought it was interesting. Lisa thought it was a cold joke, so she didn't laugh.

Life can be made do, and life can be exquisite!
