Sarah Palin - A Post Turtle?

A turtle balanced on top of a fence post

"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 it didn't get there by itself, it doesn't belong there, it doesn't know what to do while it's up there, and you just don't know what dumb ass put it up there in the first place."
