According to McCann New York, the United States Postal Service (USPS) "delivers more e-commerce packages during the holidays than anyone else." To drive this point home, the agency created a spot that features a young who discovers a hippopotamus at the zoo and becomes completely obsessed, so much so that her parents end up buying her a myriad of hippo-related gifts for Christmas. The gifts, of course, are all delivered to their house via USPS.
