Pretty much the whole city of Shawano, Wisconsin. See Inbred

Tyrell: "You notice everyone in Shawano pretty much looks the same?"
Devonte: "Well the town motto is, 'Why walk across town when you can walk across the hall?'"
Tyrell: "What does that mean?"
Devonte: "It means that your mom is your aunt and your dad is your uncle."
Tyrell: "I still don't get it."
Devonte: "Definition: Incest means your family members screw each other."
