Is it funny that a young lady's beard is so graceful that she must be a good family? Why is it funny?

Interesting. My joke was low, so I smiled. Language is different from normal language. Jokes are emotional and illogical. It's not a theory, it's a joke, and then you laugh. No, it's not a joke that you draw a conclusion through brain analysis and prove to be a joke. It's that you laughed first and analyzed it.
