Spit Out Your Coffee Funny!

I was just reading Richard Dawkins' thus far excellent The God Delusion when I came to this passage:

The journalist Andrew Mueller is of the opinion that pledging yourself to any particular religion 'is no more or less weird than choosing to believe that the world is rhombus-shaped, and borne through the cosmos in the pincers of two enormous green lobsters called Esmerelda and Keith.'

It was at the point of reading the word Keith and realising the absurdity of a lobster named Keith, or the unlikely pairing of an Esmerelda with a Keith that I had just taken a sip of too hot espresso. The espresso almost made it's way out of my mouth and onto the pages of the book, but I managed to hold it in, though I burnt my tongue in the process. But what was I to do? It was a library book.
