The doctor carrying out the procedure struck up a conversation with the old man. Eventually the topic got around to Politicians and their role as our leaders. The old farmer said, "Well, you know, most Politicians are 'Post Tortoises'.'' Not being familiar with the term, the doctor asked him, what a 'Post Tortoise' was? The old farmer said, "When you're driving down a country road and you come across a fence post with a tortoise balanced on top, that's a post tortoise." The old farmer, seeing the puzzled look on the doctor's face, continued to explain. "You know he didn't get up there by himself, he doesn't belong up there, he doesn't know what to do while he's up there, he's elevated beyond his ability to function, and you just wonder what kind of dumb ass put him up there to begin with."
