I was introduced to The Princess Bride by way of an excerpt (The Duel Scene) being included in Spider Robinson's 1981 short story anthology, The Best of All Possible Worlds,
in which he picked his favorite story, and the author of that story picked his favorite, etc.; where the author of a favorite was dead, I think Spider got a second pick, and they were off again. I had never heard of the Princess Bride before that, and shortly thereafter picked up a copy, which has been read literally to pieces in the years following. I still can't quite decide if there ever was a book by S. Morgenstern (maybe available at Mr. Trupenny's Book Emporium & Gallery), or if it's all just a product of Mr. Goldman's fertile imagination. Call me credulous.
