The Ultimate Hitchhiker's Guide Part 10

"Oh, yeah," said Zaphod, "those couple of guys."

"We picked them up in sector ZZ9 Plural Z Alpha."

"Yeah?" said Zaphod and blinked.

Trillian said quietly, "Does that mean anything to you?"

"Mmmmm," said Zaphod, "ZZ9 Plural Z Alpha. ZZ9 Plural Z Alpha?"

"Well?" said Trillian.

"Er... what does the Z mean?" said Zaphod.

"Which one?"

"Any one."

One of the major difficulties Trillian experienced in her relationship with Zaphod was learning to distinguish between him pretending to be stupid just to get people off their guard, pretending to be stupid because he couldn't be bothered to think and wanted someone else to do it for him, pretending to be outrageously stupid to hide the fact that he actually didn't understand what was going on, and really being genuinely stupid. He was renowned for being amazingly clever and quite clearly was so-but not all the time, which obviously worried him, hence the act. He proffered people to be puzzled rather than contemptuous. This above all appeared to Trillian to be genuinely stupid, but she could no longer be bothered to argue about it.

She sighed and punched up a star map on the visiscreen so she could make it simple for him, whatever his reasons for wanting it to be that way.

"There," she pointed, "right there."

"Hey... Yeah!" said Zaphod.

"Well?" she said.

"Well what?"

Parts of the inside of her head screamed at other parts of the inside of her head. She said, very calmly, "It's the same sector you originally picked me up in."

He looked at her and then looked back at the screen.

"Hey, yeah," he said, "now that is wild. We should have zapped straight into the middle of the Horsehead Nebula. How did we come to be there? I mean that's nowhere."

She ignored this.

"Improbability Drive," she said patiently. "You explained it to me yourself. We pa.s.s through every point in the Universe, you know that."

"Yeah, but that's one wild coincidence isn't it?"

"Yes."

"Picking someone up at that point? Out of the whole of the Universe to choose from? That's just too... I want to work this out. Computer!"

The Sirius Cybernetics Corporation Shipboard Computer which controlled and permeated every particle of the ship switched into communication mode.

"Hi there!" it said brightly and simultaneously spewed out a tiny ribbon of ticker tape just for the record. The ticker tape said, Hi there!

"Oh G.o.d," said Zaphod. He hadn't worked with this computer for long but had already learned to loathe it.

The computer continued, brash and cheery as if it was selling detergent.

"I want you to know that whatever your problem, I am here to help you solve it."

"Yeah yeah," said Zaphod. "Look, I think I'll just use a piece of paper."

"Sure thing," said the computer, spilling out its message into a waste bin at the same time, "I understand. If you ever want..."

"Shut up!" said Zaphod, and s.n.a.t.c.hing up a pencil sat down next to Trillian at the console.

"OK, OK..." said the computer in a hurt tone of voice and closed down its speech channel again.

Zaphod and Trillian pored over the figures that the Improbability flight path scanner flashed silently up in front of them.

"Can we work out," said Zaphod, "from their point of view what the Improbability of their rescue was?"

"Yes, that's a constant", said Trillian, "two to the power of two hundred and seventy-six thousand seven hundred and nine to one against."

"That's high. They're two lucky lucky guys."

"Yes."

"But relative to what we were doing when the ship picked them up..."

Trillian punched up the figures. They showed tow-to-the power-of-Infinity-minus-one (an irrational number that only has a conventional meaning in Improbability physics).

"... it's pretty low," continued Zaphod with a slight whistle.

"Yes," agreed Trillian, and looked at him quizzically.

"That's one big whack of Improbability to be accounted for. Something pretty improbable has got to show up on the balance sheet if it's all going to add up into a pretty sum."

Zaphod scribbled a few sums, crossed them out and threw the pencil away.

"Bat's dots, I can't work it out."

"Well?"

Zaphod knocked his two heads together in irritation and gritted his teeth.

"OK," he said. "Computer!"

The voice circuits sprang to life again.

"Why h.e.l.lo there!" they said (ticker tape, ticker tape). "All I want to do is make your day nicer and nicer and nicer..."

"Yeah well shut up and work something out for me."

"Sure thing," chattered the computer, "you want a probability forecast based on..."

"Improbability data, yeah."

"OK," the computer continued. "Here's an interesting little notion. Did you realize that most people's lives are governed by telephone numbers?"

A pained look crawled across one of Zaphod's faces and on to the other one.

"Have you flipped?" he said.

"No, but you will when I tell you that..."

Trillian gasped. She scrabbled at the b.u.t.tons on the Improbability flight path screen.

"Telephone number?" she said. "Did that thing say telephone number?"

Numbers flashed up on the screen.

The computer had paused politely, but now it continued.

"What I was about to say was that..."

"Don't bother please," said Trillian.

"Look, what is this?" said Zaphod.

"I don't know," said Trillian, "but those aliens-they're on the way up to the bridge with that wretched robot. Can we pick them up on any monitor cameras?"

Chapter 13.

Marvin trudged on down the corridor, still moaning.

"... and then of course I've got this terrible pain in all the diodes down my left hand side..."

"No?" said Arthur grimly as he walked along beside him. "Really?"

"Oh yes," said Marvin, "I mean I've asked for them to be replaced but no one ever listens."

"I can imagine."

Vague whistling and humming noises were coming from Ford. "Well well well," he kept saying to himself, "Zaphod Beeblebrox..."

Suddenly Marvin stopped, and held up a hand.

"You know what's happened now of course?"

"No, what?" said Arthur, who didn't what to know.

"We've arrived at another of those doors."

There was a sliding door let into the side of the corridor. Marvin eyed it suspiciously.

"Well?" said Ford impatiently. "Do we go through?"

"Do we go through?" mimicked Marvin. "Yes. This is the entrance to the bridge. I was told to take you to the bridge. Probably the highest demand that will be made on my intellectual capacities today I shouldn't wonder."

Slowly, with great loathing, he stepped towards the door, like a hunter stalking his prey. Suddenly it slid open.

"Thank you," it said, "for making a simple door very happy."

Deep in Marvin's thorax gears ground.

"Funny," he intoned funerally, "how just when you think life can't possibly get any worse it suddenly does."

He heaved himself through the door and left Ford and Arthur staring at each other and shrugging their shoulders. From inside they heard Marvin's voice again.

"I suppose you want to see the aliens now," he said. "Do you want me to sit in a corner and rust, or just fall apart where I'm standing?"

"Yeah, just show them in would you Marvin?" came another voice.

Arthur looked at Ford and was astonished to see him laughing.

"What's...?"

"Shhh," said Ford, "come in."

He stepped through into the bridge.

Arthur followed him in nervously and was astonished to see a man lolling back in a chair with his feet on a control console picking the teeth in his right-hand head with his left hand. The right-hand head seemed to be thoroughly preoccupied with this task, but the left-hand one was grinning a broad, relaxed, nonchalant grin. The number of things that Arthur couldn't believe he was seeing was fairly large. His jaw flapped about at a loose end for a while.

The peculiar man waved a lazy wave at Ford and with an appalling affectation of nonchalance said, "Ford, hi, how are you? Glad you could drop in."

Ford was not going to be outcooled.

"Zaphod," he drawled, "great to see you, you're looking well, the extra arm suits you. Nice ship you've stolen."

Arthur goggled at him.

"You mean you know this guy?" he said, waving a wild finger at Zaphod.

"Know him!" exclaimed Ford, "he's..." he paused, and decided to do the introductions the other way round.

"Oh, Zaphod, this is a friend of mine, Arthur Dent," he said, "I saved him when his planet blew up."
