Have you called your nana, abuela, pop-pop or lolo lately? No matter what you call them, there's no better time to pick up the phone than Grandparents' Day, held on the Sunday after Labor Day. Grandparents play a special role in our lives, helping to raise new generations, passing down family history and sharing the wisdom of their experience. Wisdom is not always indicated by a thick Wilford-Brimley-esque mustache, but whiskers do lend a certain esteemed quality. Perhaps that's why these Atlantic walruses look like they're about to tell you why they voted for Hubert Humphrey.
