The old rancher said, "Well, as I see it, most politicians are 'Post Turtles'.''
Not being familiar with the term, the doctor asked him what a 'post turtle' was. The old rancher said, "When you're driving down a country road and you come across a fence post with a turtle balanced on top, that's a post Turtle."
The old farmer saw the puzzled look on the doctor's face so he 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 arse put him up there to begin with.
Thanks to Mr TSK for sharing.
