BTW - the group who did this are called "The Chaser" and they take the mickey out of everyone, not just the Yanks.
Recently they made the NSW Police Force look like a bunch of geese by
breeching APEC security, after driving a convoy of official looking cars through a series of police roadblocks, simply by virtue of having the Canadian flag on their cars - despite the fact that one of them was dressed as Osama bin Laden!
