Arthur: How did we get here?
Ford: We hitched a lift.
Arthur: Excuse me, are you trying to tell me that we just stuck out our thumbs and some green bug-eyed monster stuck his head out and said "Hi, fellas, hop right in, I can take you as far as the Basingstoke roundabout"?
Ford: Well the thumb's an electronic sub-etha device, the roundabout's at Bernard's Star six light years away, but otherwise that's more or less right.
Arthur: And the bug-eyed monster?
Ford: Is green, yes.
