Who is Sarah Palin?

An old Texas farmer is talking to his new neighbor who just moved out from the city. They get to talking about politics and the younger man asks the farmer what he thinks about Sarah Palin.

"Well", he drawls, "I think she's pretty much like a post turtle".

"What's a post turtle?" the younger man asks, "I've never heard of that."

"Well," says the farmer, "every once in a while, I'm drivin' down the road in my pickup and I see a big ole turtle sittin' up on a fencepost. Now that turtle doesn't belong up there, he has no idea how to get down. And I always wonder, what the hell kind of jackass put him up there in the first place."
