"The fields have eyes, and the woods have ears."
Or a favourite of mine :).
"What is better than wisdom? Woman. And what is better than a good woman? Nothing."
I still have a copy of this book that my grandmother gave me. She had an old edition that was written in its original Middle English. Considering its age I think it is a good and funny book, built up of 20 stories if I remember correctly. $1.50 seems live a very good price for such a classic book, that's one of the great things about visiting used bookshops, you can pickup some wonderful and rare books for a small price.
I actually came upon that first line you quoted and was trying to remember where I'd recently seen it, then checking this thread it dawned on me:P. I finished The Knight's Tale recently and have begun The Miller's Tale. I forgot how richly funny these bawdy stories were, great fun.
