While stitching a cut on the hand of an old farmer, whose hand was caught in the squeeze gate while working cattle, the doctor struck up a conversation with the old man.

Eventually the topic got around to politicians and their role as our leaders.

The old rancher said, “Well, most politicians are ‘Post Turtles’.”
Not being familiar with the term, the doctor asked what a ‘post turtle’ was.
The old rancher said, “When you’re driving down a country road you come across a fence post with a turtle balanced on top, that’s a post turtle.”
Seeing the puzzled look on the doctor’s face so he explained.

“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 arse put him up there to begin with.”

Best explanation of a modern politician I’ve ever heard.
