People just love to play with words

I was reading along happily in Christopher Moore's "Lamb" when suddenly a thought popped into my head. (It was completely lost and alone in there I assure you. I think it might have been depressed by the layer of dust and the cobweb covered skeleton of the last thought. Hopefully it won't hang out too long waiting for another one to come along so they can wander off and do lunch, it might starve.) Are all the bovines in China simply trying to tell us that we're asking non-sense questions?

Shouldn't "gently moo" be "gently mu" or "gently mou"?
