What episode of * * * did Li tell jokes to Cixi?

In the street, a well-dressed salesman stopped a man and asked, "Sir, would you like to spend 200 dollars on this bottle of mouthwash?"

The man said in horror, "Are you crazy? That was a robbery. 1

The salesman seemed very hurt, and then asked, "Sir, because you are a little angry, I decided to sell it to you at a 50% discount. How about 100 dollars? " The man refused: "You must be crazy, go away."

So the salesman reached into his briefcase, took out two pieces of nut chocolate, put one in his mouth and chewed it. He said to the angry guy, "Sir, because I have angered you, please have a chocolate."
