For over 20 years, one of the longest running gags on The Simpsons was the mystery over what state the famous yellow family has lived in. Well now you can wonder no more. In a recent interview with Smithsonian Magazine, series creator Matt Groening finally revealed the location of the most dysfunctional town on TV.

"Springfield was named after Springfield, Oregon. The only reason is that when I was a kid, the TV show Father Knows Best took place in the town of Springfield, and I was thrilled because I imagined that it was the town next to Portland, my hometown. When I grew up, I realized it was just a fictitious name. I also figured out that Springfield was one of the most common names for a city in the U.S. In anticipation of the success of the show, I thought, 'This will be cool; everyone will think it's their Springfield.' And they do."

So there you have it. After all these years we finally have a definite answer from the man himself. Are you satisfied with the result, or would you have liked to leave it to your imagination?
