When dealing with mysteries that are embedded into hit TV shows, it’s the one that’s embedded into perennial animated favorite The Simpsons that stands high above the rest. The mystery? WHICH Springfield, exactly, does this never-aging family reside in?!

OK, so perhaps it’s not all that important a mystery. Still…the question evolved into a long-running joke which has maddened fans for the over two decades the show has existed, leading many to go to great lengths just to figure out where it might be.

Instead of going through all that, as it turns out, the way to find out which Springfield is the right Springfield was to just be very patient and wait for creator Matt Groening to tell us the answer. Whodathunkit?
