Bush pointed out the Group of Eight summit of industrialized nations this year would be in Scotland.
He added: "I worked there as a 14-year-old kid. I left Texas for Scotland to work on a sheep farm. And I'm riding a bike, taking this one sheep, you know, from here to there and I said OK, fine, and a big tour bus stops. And they got off and a woman with a Texas accent said, 'look at the little Scottish boy.'"
