As US comedian Sandra Bernhard brings her new stage show to Dublin and London Edward Helmore finds that her act has new targets - George Bush and his 'alien lizards'

"Americans are lazy," says Bernhard. "They don't want to look at the larger picture. They don't have a concept of how the world interacts with America or how the world interacts with itself. That makes it easier for them to be denigrating to the rest of the world because it makes them feel safer. It's a little scary to be in a country so detached from reality and so ready to buy into the propaganda that the enemy is out there lurking, ready to attack us again."
