The other day, I saw the episode where Homer joins the Navy and is in a submarine. It's the one where he uses Barts' earring to plug the hole.
Anyway, at one point, there is a map of the world, and it shows Homer saying "left....left....left........nah, go right".
When it's going left, it looks to be heading for a state in the upper left section of America....there is a dot or something on the map that says "Springfield"...I'm guessing Washington....it's just a guess as I didn't tape it....plus I'm Australian and don't know all the states.
I'm gonna go look for screenshots now but so far, this is all I have.
Any help ?
