I don't recall seeing this on here before, and it's becoming a favorite analogy of mine as time goes by.

While suturing the hand of a 75 year old rancher whose hand had been 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, “Well, 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'”. Seeing that the doctor was still puzzled, he continued to explain. "Now 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."

Seems to be about the best explanation I've heard yet.
