One big (straight, gay, multi-cultural, traditional) happy family.
The Pritchett-Dunphy-Tucker clan is a wonderfully large and blended family. They give us an honest and often hilarious look into the sometimes warm, sometimes twisted, embrace of the modern family.
The Dunphys try to persuade the perfect couple to move in next door, Manny dates the daughter of Jay's biggest nemesis, and Mitchell and Cameron try to get Lily a new teacher.
