Arthur Dent is a completely normal, though very unsuccessful, Englishman going through the motions of life as we all do; however, that is all about to change. In just a few hours, the Earth will be destroyed for seemingly no reason at all. The Hitchhiker's Guide to the Galaxy, written by Douglas Adams, follows Arthur as he attempts to fit in in the universe that destroyed his planet for a highway. His long time friend, and secretly Alien, Ford Prefect, saves Arthur and latches on to one of the enormous spaceships that incinerated Earth just seconds before hand. As they travel, Ford constantly refers back to the all holy guide of traveling spacemen, The Hitchhiker's Guide to the Galaxy, which gives tips and information on how to survive the cold depths of space. As they travel, they meet up with the President of the Universe, Zaphod Beeblebrox, who with him has an acquaintance of Arthur's Tricia McMillan, and together, they travel the universe in search of the "Answer to the Ultimate Question of Life, the Universe and Everything". Their quest ultimately leads them to a super computer with the answer. The answer is 42. This of course is no help without the original question, which the computer tells them is in another computer disguised as a planet. The computer then reveals that this planetoid was called Earth. In shock, Arthur is then kidnapped by two Earth mice who secretly are the original creators of Earth. Because Earth had finished formulating the question, Arthur's brain contained it. The mice attempt to kill Arthur and dissect his brain, but Ford and the gang escape with Arthur and decide they are hungry and set course for the "Restaurant at the End of the Universe". The mice, too lazy to build another earth and wait 10,000,000 years, make up the question, "How many roads must a man walk down?"
Do you think Adams was making a point when he made Earth a computer?
