An extraordinary tale of an 18th Century family
Have you wanted to read a book where the author decides to "rip out" one of the chapters, or leaves a blank page for you to 'draw' one of the characters? Would you enjoy a story which takes many chapters before the hero manages to be born? This 18th-Century tale is touchingly told. The characters are real, and fascinating. It's not their fault that their story is frequently and impishly interrupted by outlandish "digressions" on the part of an author so creative that his modern descendants are considered to be Joyce and Beckett, as well as many others. Would you enjoy a chapter on Chapters? About buttonholes? About whether parents and their children are kin to each other? A chapter on curses? Poor Laurence Sterne has so much trouble getting two of his characters down the stairs that he finally calls in a "critic" to help! Advice on reading such an unusual, even unique, book: read the first several chapters, then stop and reread them. Continue that process and soon the book will feel quite familiar, and that's when the fun really starts. The Oxford World's Classics edition follows the first edition of the book, and is preferred. Amazon also offers the fully-annotated edition, the "Florida" edition, in three volumes. A caution about the Everyman hardcover edition: they reprinted a later edition which groups Tristram Shandy into three volumes, not nine. And then they renumbered all the chapters! That's OK unless you read secondary sources that refer you to Book VII, Chap 4: good luck ever finding it.

A Total Sham-dy
What in the hell was this lunatic yammering about for all those 650 pages? What is the deal with his obession with noses, penises, and hobby-horses, hobby-horses, hobby-horses? Why does anyone consider it amusing when a writer keeps telling you he's going to get somewhere, but never does? Why is it entertaining at all to have blank chapters? Why is that cute? Why is that interesting? Who finds this funny? Who finds anything funny here at all? Why does this book of endless, mindless prattle, blabber, and piffle tickle anyone at all? Who finds digression to be enjoyable in literature? You? Why? Why? Tell me! I checked the ratings on Goodreads. This is what it showed: 5 stars: 33%, 4901 4 stars: 28%, 4064 3 stars: 22%, 3268 2 stars: 9%, 1414 1 star: 5%, 848 Meaning: 95% of these readers are flock-following, digression-loving, hobby-horse riding loonies who have swallowed the Kool-aid. There is nothing here but vacuous thundergunk. Pure, putrid unenertaining garbage. If I would have laughed once - just once - during the reading of this book, I would have given it a whole extra star, but it couldn't even do that. I give him one star for spelling Tristram's name right, and even then, it's a made-up name anyway, so I may have been hoodwinked as well.

Laurence Stern is still one of the most creative writers ever
This review is not about the words and images inside the book. This is about the fact that, when I removed the book from its packaging, the book's cover had too many creases and bends in it, both front and back, for my taste. Although I do think that Laurence Sterne might have smiled at my response, I don't think the creases were a type of samizdat (think Alexander Solzhenitsyn) added by a disgruntled/creative employee at Amazon. If this doesn't make any sense to you, or seems to be a silly mountain out of a molehill compliant, you will love the book.

A Few Thoughts on Tristram Shandy by Laurence Sterne
Shandy is an amazing book. More than anything it made me think of a late 1990s vibe with Seinfeld and David Foster Wallace. I can imagine the discourse that must have grown up around it. It I about memory and storytelling but also about nothing but also childbirth and siege warfare. I’m glad I read it; it was worth it even if it took a while.
