Maybe you know about "Zhao Zhou's Dog" also known as the #mu #koan from #ZenBuddhism.

First time I heard it, I thought Mu (Wu) was the answer of the dog.
- Does a dog have Buddha nature or not?
- Why don't you ask a dog? You know what it would say?
- ...
- Wu(f)
And to be honest, since then I find this reading of the koan funnier, but also more inclusive in a non-specist way than usual commentaries 😁
