An old farmer was getting his hand stitched up after an accident at his cattle farm.
He and the doctor start into conversation, which leads into politics.
The old farmer explained, "Well, as I see it, most politicians are 'Post Turtles'."
Not being familiar with the term, the doctor asked what a 'post turtle' was. The old farmer explained as best he could, "When you're driving down a country road and you come across a fence post with a turtle on top, that's a 'post turtle.'
The doctor remained puzzled. The farmer continued further.
"You know he didn't get up there by himself, he doesn't belong up there, he doesn't know what to do while up there, he's elevated beyond his ability to function, and you just wonder what kind of dumb arse put him there to begin with."
