While suturing a cut on the hand of a 75 year old rancher 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 Obama and his role as our president.
The old rancher said, 'Well, ya know, Obama is a 'Post Turtle".
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 rancher 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 ass put him up there to begin with."

Best explanation I've heard yet of Obama.
