"Excuse me?" said Arthur. "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?"
"Well," said Ford, "the Thumb's an electronic sub-etha signalling device, the roundabout's at Barnard's Star six light years away, but otherwise, that's more or less right."
"And the bug-eyed monster?"
"Is green, yes."
"Fine," said Arthur, "when can I get home?"
"You can't," said Ford Prefect, and found the light switch.
"Shade your eyes ..." he said, and turned it on.
Even Ford was surprised.
"Good grief," said Arthur, "is this really the interior of a flying saucer?"
Prostetnic Vogon Jeltz heaved his unpleasant green body round the control bridge. He always felt vaguely irritable after demolishing populated planets. He wished that someone would come and tell him that it was all wrong so that he could shout at them and feel better. He flopped as heavily as he could on to his control seat in the hope that it would break and give him something to be genuinely angry about, but it only gave a complaining sort of creak.
"Go away!" he shouted at a young Vogon guard who entered the bridge at that moment. The guard vanished immediately, feeling rather relieved. He was glad it wouldn't now be him who delivered the report they'd just received. The report was an official release which said that a wonderful new form of spaceship drive was at this moment being unveiled at a government research base on Damogran which would henceforth make all hyperspatial express routes unnecessary.
Another door slid open, but this time the Vogon captain didn't shout because it was the door from the galley quarters where the Dentrassis prepared his meals. A meal would be most welcome.
