This is a story about two friends who've known each other for a while. At least Arthur Dent thinks so until Ford Prefect reveals that he's actually an alien and that the world is about to end! Not long after their conversation, a Vogon spaceship appears and announces that earth will be destroyed shortly because it is in the way of a new intergalactic highway bypass that is being built through our galaxy. Ford and Arthur manage to board the ship before the earth is demolished, and they are quickly discovered - ejected into space by the Vogon captain!
