Family Guy: Season 2, Episode 18

2 - 18: E. Peterbus Unum

When Peter goes to City Hall for a pool permit, he discovers that the Griffin house is not located in Quahog---or even in the U.S. And so a new nation---Petoria---is born. Not surprisingly, Peter (voice of series creator Seth MacFarlane) proves to be a saber-rattler, and that leads to a cooling in U.S.-Petorian relations.
