A country doctor is suturing a laceration on the hand of an old farmer.

Old man: "All you need to know about politics is that young George Bush is a post turtle."

Doctor: "Oh? What is a post turtle?"

Old man: "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."
"You know he didn't get there by himself, he doesn't belong there, he can't get anything done while he's up there, and you just want to help the poor dumb bastard get down."
