Once upon a time the Democrats and Republicans decided to have their Presidential debate in the American Heartland. So the stage was built against the backdrop of a Midwestern farm. But the debate couldn't get started because of all the flies buzzing around the heads of the two Presidential candidates. Both candidates demanded to know why the flies wouldn't leave, so the farmer (who owned the farm where the debate was being held) explained to them, "Well, those are called circle flies. They always circle around the back end of horses." In unison both candidates angrily replied, "Hey, are you saying that I'm a horse's behind?" The farmer answered, "Oh no! I would never call someone a horse's behind. But it's hard to fool them flies though."
