In regard to the town's name being a sly joke, this is also reinforced in the first episode of "Green Acres": When Lisa Douglas first hears the name of the town, she mispronounces it "Hootersville". The laugh track appeared to play it as due to her thick accent.  (Anonymous User, but I remember the original tv ads for Green Acres including this clip in the commercial.
