Invention of the week: Zip Enhancer
Amy works with an older couple, the McGanns, and feels sorry about their loss of vitality. Wayne invents a mechanism to transfer some of Diane and Wayne's vitality to the McGanns. As the McGanns enjoy their youth, and continue to get younger, they leave Wayne and Diane to wither in their premature old age, as they continue to get older. Nick and Amy pursue the McGanns to get the situation reversed.
