Query: The most entertaining language book you'll ever read!

I recently bought another copy of this book as the first one has fallen to pieces from much use. It's not your typical language text and not for rank beginners but it certainly gets the points across in an easy and often humorous manner. The lack of an index is a minor annoyance, and who has ever died from having to flip through the pages of a book?
