As long as you're sitting, you might as well be doing some thinking—or so goes the reasoning at the Bathroom Readers' Institute. This collection of brain stretchers from Uncle John invites you to test your mental mettle, whether you try one puzzle every day, or do all 365 at your leisure. You'll find traditional logic puzzles, word ladders (converting words to other words, one letter at a time), mysteries (specially invented by Inspector Commodius Loo), wild & woolly wordies (visual word puzzles), echoes (fun with homophones), and cryptograms (in various guises).
