The hitchhikers quote suddenly got me thinking. I'd always sort of asumed that Douglas Adams was writing for a British audience (I'm sure the radio show at least was) and British money isn't green. Was it previously green? Is there some other significance to green? Did it get translated for American's, and if so, what does the British version say? The first few Harry Potters were translated for American release. It was kind of amusing reading the British version, where Duddly's first word was "shan't" while in the American version it's "won't"
