She thinks that humans and dinosaurs lived together!

Granted, the story's source is ultimately a casual conversation with someone disinclined to report favorably about her in any case, but since the McCain campaign won't let her speak all too often to the press, what else do we have to go on? So, as officially as can be stated under the circumstances, Sarah Palin is on the record for believing that humans and dinosaurs walked the Earth at the same time. Is this a joke?
