Two brothers went into a rice restaurant, where they were served salted duck eggs. The younger brother asked the older brother:
– Why is this duck egg so bitter?
The older brother replied:
– If you say that, people will laugh at you! You don’t even know what a salted duck egg is.
The younger brother questioned again:
– So where do salted duck eggs come from?
The older brother, trying to sound knowledgeable, said:
– How can you be so silly! It’s not that hard to understand. The salted duck lays salted duck eggs, where else would they come from!
