The Fools' Guild of Ankh Morpork is a busy lot so it's not surprising they need this handy diary to help them keep track of their hectic schedule bringing joy and mirth into the hearts of the city's residents.This is yet another of the ever increasing range of spin-off products spawned by Terry Pratchett's unstoppable Discworld series and serves both as a hilarious collectors item and fully functioning diary. Written by Pratchett and regular collaborator Stephen Briggs, it is the footnotes and introductory notes that make this worth the purchase as both authors squeeze some side splitting gags from very little space. Adverts, memos, excerpts from the Fools' Guild Rule Book and even mock exam papers for those hoping to become a qualified fool all sparkle with that special Pratchett magic: Guild Memorandum 169/010--Bladders (the ones on a stick). Please note that there is NOT an endless supply of these items. In some countries they are considered a delicacy. From now on requests for a new bladder must be accompanied by the old bladder and form BR/RU/1a, countersigned by two senior members of Council. We are not made of money.Guild Memorandum 1J4/783--Owing to the fracas on the fourth floor last night, all members are reminded that pushing another clown off the roof is allowable only if it is VERY FUNNY INDEED (ie. higher than 14 on the Shumann-Blinbko scale). DROLL, A BIT OF A LAUGH and QUITE AMUSING are not sufficient grounds and it is only because Sicko Sidney landed on a trampoline that certain Brothers are not facing a prolonged interview with the Bloody Fools.The diary is liberally and beautifully illustrated by Paul Kidby, another Discworld regular, and it is a compulsory addition for the fans' ever growing collections. But who is going to want to spoil it by using it for its intended purpose? --Jonathan Weir
