Plot Krusty Burger launches a new Vegie Burger made from Barley grown in Ogdenville which turns out to be tainted causing mass vomiting in Springfield. Due to the economic slump in Ogdenville, they all travel to Springfield for work, mostly doing odd jobs for people such as fixing roofs, gardening and such. <br /><br />Trying to impress a bunch of Ogdenvillian kids, Bart accidentally breaks his arm, but is unable to get hospital treatment because all the Ogdenvillian people are taking too much of the Springfieldian resources. To get rid of the Ogdenvillians, Springfield closes the borders, where Chief Wiggum and Lou cant manage it by themselves, and as such hire a group of Vigilantes to patrol instead, they include Homer, Lenny, Carl, and Gil among others. <br /><br />Still unable to keep the Ogdenvillians out, they propose to build a fence around the border where after it's completion, the Springfieldians miss their Ogdenvillian neighbours and allow them to return to Springfield through an unauthorised door and have a party.
