One Thursday morning, Arthur Dent discovers that his house is to be immediately demolished to make way for a bypass. He tries delaying the bulldozers by lying down in front of them. Ford Prefect, a friend of Arthur’s, convinces him to go to the pub with him. Over a pint of beer (as “muscle relaxant”), Ford explains that he is an alien from a planet in the vicinity of Betelgeuse, and a journalist working on the Hitchhiker’s Guide to the Galaxy, a universal guide book, and that the Earth is to be demolished later that day by a race called Vogons, to make way for a hyperspace bypass. Suddenly, a Vogon Constructor Fleet appears in the sky and destroys the planet. Ford saves himself and Arthur by hitching a ride on a Vogon ship. The two are found and forced to listen to poetry. They are then thrown out of an airlock, but are picked up by the starship Heart of Gold. They find Ford’s “semi-half brother” Zaphod Beeblebrox, the President of the Galaxy. He has stolen the ship along with Tricia “Trillian” McMillan, an Earth woman whom Arthur had met previously, and Marvin the Paranoid Android.
