In 12th grade English class in 1958 I sat on the back row reading a paperback copy of PEYTON PLACE.

Someone told me that I would not pass reading that book in class.
Mr. W our teacher spoke up and said, "Not so. In fact Joe after you finish that I would like to read it. And I will tell you of a book that is even more notorious. He told me to read The Decameron by Boccaccio.
