A small town that has no football team, and that no one wants to live in or visit, except during the annual Cheeseburger in Caseville festival, which brings in all the money to keep the town running for the rest of the year because people hope to be able to meet Jimmy Buffett. Whenever you leave that place, you feel severely disappointed, because there are no unicorns. And back to the point about Jimmy Buffett, Vogie is not that guy.
Dude 1: Hey Dude you wanna go to Caseville?
Dude 2: Yeah dude its cheeseburger there!
Dude 1: I've never been to Cheeseburger
Dude 2: Never mind. Its in Caseville
