Zen Buddhism is a unique faith inasmuch as it can live comfortably with contradictions. The Zen answer to a question that cannot be answered straight is 'Moo' (also spelled 'Mu'), a word that means 'nothing' or 'your-question-cannot-be-answered-as-it-is- based-on-incorrect-assumptions'.
A monk asked Joshu: "Has a dog Buddha-nature or not?"
Joshu answered: "Moo."
"Have you stopped beating your wife?"
"Moo!"
