From the middle ages onwards, the use of scatology in social commentary has been a central feature of a certain type of literature. From the giants Garguantua and Pantegruel of Rabelais to the literary criticism of Smollet, DeFoe, Swift and many more, the shock effect of a good dose of toilet humour has the potential to shake up the sediments and confront the complacent. The protagonist is Uncle Tommy MacTavish, an aging, chronically constipated wannabe intellectual who lives on the fringes of his Scottish Highland home. He is a Walter Mitty of the WC, seizing the day in his own unique manner as he caustically reflects on the follies and foibles of his fellow men and women. I warn you, this book is not for those who are fainthearted or easily offended by lavish descriptions of bowel movements and toilet troubles. However, if you like such things, you are in for a rare and recommended treat
