And why do we kiss under mistletoe? And why are blueprints blue? I can think of no other book which is brave enough to answer these questions. Fans of the other "Imponderables" books will not be disappointed by this one, as it is similar in nature to the rest of the series. Readers who have never before delved into the realm of Imponderables are also in for a treat. "Why Do Dogs Have Wet Noses?" is light, clever, and just plain funny. However, I must warn you that you may possibly learn something from it. Who would have thought that a book that is basically a series of odd questions and answers could be so thoroughly enjoyable?
