Ford Prefect

His most recent assignment was to an insignificant planet in an unfashionable end of the galaxy. Intending to stay for a week, he was stranded for fifteen years.

He chose his name in the belief that he would blend in to the native culture nicely. This was a slight translation problem. His original name is "only pronounceable in an obscure Betelgeusian dialect".

Although sometime worse for wear due to excessive consumption of Ol' Janx Spirit, he always knows where his towel is.
