A hitchhiker is an individual who travels the universe without the use of a ship of their own. Popular hitchhikers are Arthur Dent and Ford Prefect. Contrary to popular belief, Zaphod Beeblebrox is not technically a hitchhiker because he owns a ship which he has stolen (see: heart of gold)

Also, it is a common misconception that a hitchhiker is someone who knows where his towel is. This fact is only true to froody (cool and together) hitchhikers, giving rise to the popular expression "that frood really knows where his towel is". Arthur Dent and Tricia McMillan are two examples of "froody" hitchhikers
The best hitchhikers have all seen the restaraunt at the end of the universe.

A being, human or otherwise, that randomly asks strangers for rides in transportation devices when in need of such a service. Their destination can vary, parts of the galaxy, parts of America, the important places mostly. Most are fearless, yet stupid and reckless.
