Apparently, everyone misinterpreted Matt Groening's interview with Smithsonian Magazine in which he said Springfield, Oregon, was the Simpsons' hometown. After Sunday night's opening credits teased, "Now entering Oregon," the show's producers took to Bart's blackboard in an ambiguous attempt at keeping Springfield shrouded in mystery: "The true location of Springfield is in any state but yours."
"I have no idea where the hell it is," Groening said. "Like all Americans, I flunked geography."
