PHOENIX (AP) — A new book written by Arizona Rep. Gabrielle Giffords and her husband reveals the injured Democrat could say only two things to a visiting President George H.W. Bush, "Wow!" and another word she had been uttering frequently at the time, "chicken."Months later, when she was shown photos of famous people to see if she recognized faces, Giffords looked at Arnold Schwarzenegger and replied, more or less accurately: "Messin' around. Babies."The episodes are recounted in the memoir titled "Gabby: A Story of Courage and Hope." The Associated Press purchased an advanced copy of the book written from the perspective of Giffords' husband, former astronaut Mark Kelly. But Giffords herself delivers the last chapter in which she says her goal is to get back to Congress as she recovers from the Jan. 8 attack outside a Tucson grocery store that left six dead.
