Ford gaped at him in astonishment for a moment, and then roared with laughter.

“That’s it,” said Zaphod with the sort of grin that would get most people locked away in a room with soft walls.

“But why?” said Ford. “What’s so important about having it?”

“Dunno,” said Zaphod. “I think if I’d consciously known what was so important about it and what I would need it for it would have showed up on the brain screening tests and I would never have passed.[1] I think Yooden told me a lot of things that are still locked away.”

“So you think you went and mucked about inside your own brain as a result of Yooden talking to you?”

“He was a hell of a talker.”

  1. My idea: "if I had known everything, I may not have gone through with anything." In other words, if we knew everything about life, really understood everything, we may find no reason to go through with it and so arrive at certain results and consequences that we could not have foreseen before embarking. ↩︎
