Arthur Dent awakes one morning and finds his house is going to be demolished, but for Arthur, the demolition of his house is only the beginning, when his friend, eccentric Ford Prefect reveals to Arthur he is not a human and he is a alien from a planet called Beetleguise and is a researcher for a electronic book called "The Hitch-Hikers Guide to the Galaxy." Ford saves Arthur when the Earth is destroyed by the Vogans so the Vogons can begin construction of a new hyperspace bypass. Joined by Ford's cousin, Zaphod Beeblebrox, a two-headed hippie-like former intergalactic President, Intelligent Human woman Trillian and Marvin, a depressed paranoid android, Arthur and Ford embark on a intergalactic adventure, which leads them to The Restraunt at the End of the Universe, discovering the creation of Earth and discovering the meaning of life.

Zaphod's second, remote controlled mechanical head constantly malfunctioned on the set, resulting in it lolling to the side or staring blankly into the distance.

Marvin:
[repeated line] Life. Don't talk to me about life.

Crew or equipment visible: When Ford and Arthur meet Zaphod for the first time in the series (near the end of the first episode) the operator of Zaphod's third arm can be seen (they can be seen in other episodes, too, notably the third)
