Relaxing in a wickerwork sun chair, Zaphod Beeblebrox said, “What the hell happened?”

“Well, I was just saying,” said Arthur lounging by a small fish pool, “there’s this Improbability Drive switch over here…” he waved at where it had been. There was a potted plant there now.

“But where are we?” said Ford, who was sitting on the spiral staircase, a nicely chilled Pan Galactic Gargle Blaster in his hand.

“Exactly where we were, I think…” said Trillian, as all about them the mirrors suddenly showed them an image of the blighted landscape of Magrathea, which still scooted along beneath them.

Zaphod leaped out of his seat.

“Then what’s happened to the missiles?” he said.

A new and astounding image appeared in the mirrors.

“They would appear,” said Ford doubtfully, “to have turned into a bowl of petunias and a very surprised-looking whale…”

“At an Improbability factor,” cut in Eddie, who hadn’t changed a bit, “of eight million, seven hundred and sixty-seven thousand, one hundred and twenty-eight to one against.”
