An old Texan was chatting with his doctor and said, "Well, ya know, Republicans are 'post turtles.'"
Not being familiar with the term, his 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 man saw a puzzled look on the doctor's face, so he continued to explain.
"You know he didn't get there by himself, he doesn't belong there, he doesn't know what to do while he's up there, and you just want to help the dumb thing get down."
