"I always thought that about the Garden of Eden story," said Ford.

"Eh?"

"Garden of Eden. Tree. Apple. That bit, remember?"

"Yes of course I do."

"Your God person puts an apple tree in the middle of a garden and says do what you like guys, oh, but don't eat the apple. Surprise surprise, they eat it and he leaps out from behind a bush shouting `Gotcha'. It wouldn't have made any difference if they hadn't eaten it."

"Why not?"

"Because if you're dealing with somebody who has the sort of mentality which likes leaving hats on the pavement with bricks under them you know perfectly well they won't give up. They'll get you in the end."
