Rabelaisian!

Every book has an owl in it. Sometimes the owl doesn't appear until just before the ending. Sometimes the book will quote another book with an owl in it, making it a "twofer." Both of these things are true for THE BOOK OF LEGENDARY LANDS by Umberto Eco, which in its last chapter quotes Rabelais on the subject of an island inhabited by birds who "farted like men." Rabelaisian! "Some of them were all over white as swans, others as black as crows, many as grey as owls, others black and white like magpies, some all red like redbirds, and others purple and white like some pigeons."
