Since someone mentioned Weird Al, I have one that is just plain impossible. Amish Paradise. Can anyone even find a scene that looks Amish in the show?
You don't have to take it literally. Just find things that are, perhaps, simple and old-fashioned. Like Clark's manners.
Besides, you've got the Kent farm, which is more modern than you might expect, but is still fairly pastoral.
Or you could do the whole thing sarcastically, filled with the weirdest sci-fi stuff in the show. Lasers instead of butter churns, etc.
