Alice and Bob
The Alice and Bob After Dinner Speech
given at the Zurich Seminar, April 1984,
by John Gordon, by invitation of Professor James Massey
Good evening Ladies and Gentlemen.
There comes a lowest rate copy of acrobat 9 pro time when people at a technical conference like this need something more relaxing. A change of pace. A shift of style. To put aside all that lowest rate copy of acrobat 9 pro work stuff and think of something refreshingly different.
So let’s talk about coding theory. There are lowest rate copy of acrobat 9 pro perhaps some of you here tonight who are not experts in coding theory, but rather have lowest rate copy of acrobat 9 pro been dragged here kicking and screaming. So I thought it lowest rate copy of acrobat 9 pro would be a good idea if I gave you a lowest rate copy of acrobat 9 pro sort of instant, five minute graduate course in coding theory.
Coding theorists are lowest rate copy of acrobat 9 pro concerned with two things. Firstly and most importantly they are concerned with the lowest rate copy of acrobat 9 pro private lives of two people called Alice and Bob. In theory papers, whenever a lowest rate copy of acrobat 9 pro coding theorist wants to describe a transaction between two parties he doesn’t call then lowest rate copy of acrobat 9 pro A and B. No. For some longstanding traditional reason he calls them Alice and lowest rate copy of acrobat 9 pro Bob.
Now there are lowest rate copy of acrobat 9 pro hundreds of papers written about Alice and Bob. Over the lowest rate copy of acrobat 9 pro years Alice and Bob have tried to defraud insurance companies, they’ve played poker for high stakes by mail, and they’ve exchanged secret messages over tapped telephones.
If we put together all the lowest rate copy of acrobat 9 pro little details from here and there, snippets from lots of papers, we get a lowest rate copy of acrobat 9 pro fascinating picture of their lives. This may be the first time a lowest rate copy of acrobat 9 pro definitive biography of Alice and Bob has been given.
In papers written by American authors Bob is lowest rate copy of acrobat 9 pro frequently selling stock to speculators. From the number of stock market deals Bob is lowest rate copy of acrobat 9 pro involved in we infer that he is probably a stockbroker. However from lowest rate copy of acrobat 9 pro his concern about eavesdropping he is probably active in some subversive enterprise as well. And from lowest rate copy of acrobat 9 pro the number of times Alice tries to buy stock from him we infer she is lowest rate copy of acrobat 9 pro probably a speculator. Alice is also concerned that her financial dealings with Bob are lowest rate copy of acrobat 9 pro not brought to the attention of her husband. So Bob is lowest rate copy of acrobat 9 pro a subversive stockbroker and Alice is a two-timing speculator.
But Alice has lowest rate copy of acrobat 9 pro a number of serious problems. She and Bob only get to lowest rate copy of acrobat 9 pro talk by telephone or by electronic mail. In the country where lowest rate copy of acrobat 9 pro they live the telephone service is very expensive. And Alice and lowest rate copy of acrobat 9 pro Bob are cheapskates. So the first thing Alice must do is lowest rate copy of acrobat 9 pro MINIMIZE THE COST OF THE PHONE CALL.
The telephone is lowest rate copy of acrobat 9 pro also very noisy. Often the interference is so bad that Alice and lowest rate copy of acrobat 9 pro Bob can hardly hear each other. On top of that Alice and lowest rate copy of acrobat 9 pro Bob have very powerful enemies. One of their enemies is the lowest rate copy of acrobat 9 pro Tax Authority. Another is the Secret Police. This is a pity, since their favorite topics of discussion are lowest rate copy of acrobat 9 pro tax frauds and overthrowing the government.
These enemies have lowest rate copy of acrobat 9 pro almost unlimited resources. They always listen in to telephone conversations between Alice and lowest rate copy of acrobat 9 pro Bob. And these enemies are very sneaky. One of their favorite tricks is lowest rate copy of acrobat 9 pro to telephone Alice and pretend to be Bob.
Well, you lowest rate copy of acrobat 9 pro think, so all Alice has to do is listen very carefully to lowest rate copy of acrobat 9 pro be sure she recognizes Bob’s voice. But no. You see Alice has lowest rate copy of acrobat 9 pro never met Bob. She has no idea what his voice sounds like.
So you lowest rate copy of acrobat 9 pro see Alice has a whole bunch of problems to face. Oh yes, and lowest rate copy of acrobat 9 pro there is one more thing I forgot so say - Alice doesn’t trust Bob. We don’t know why she doesn’t trust him, but at some time in the lowest rate copy of acrobat 9 pro past there has been an incident.
Now most people in Alice’s position would give up. Not Alice. She has lowest rate copy of acrobat 9 pro courage which can only be described as awesome. Against all odds, over a lowest rate copy of acrobat 9 pro noisy telephone line, tapped by the tax authorities and the secret police, Alice will happily attempt, with someone she doesn’t trust, whom she cannot hear clearly, and lowest rate copy of acrobat 9 pro who is probably someone else, to fiddle her tax returns and lowest rate copy of acrobat 9 pro to organize a coup d’etat, while at the lowest rate copy of acrobat 9 pro same time minimizing the cost of the phone call.
A coding theorist is someone who doesn’t think Alice is crazy.
Information
The other thing coding theorists are lowest rate copy of acrobat 9 pro concerned with is information. Nothing else is like information. Information is lowest rate copy of acrobat 9 pro very peculiar stuff. It can both be created and destroyed. You can lowest rate copy of acrobat 9 pro steal it without removing it. You can often get some just by guessing. Yet it lowest rate copy of acrobat 9 pro can have great value. It can be bought and sold.
One type of information is called Money.
There are lowest rate copy of acrobat 9 pro people who refuse to concede that money can be created and lowest rate copy of acrobat 9 pro destroyed. They spend their entire lives altering records and making adjustments to lowest rate copy of acrobat 9 pro ensure that every time a bit of money leaves some place, an lowest rate copy of acrobat 9 pro equal bit seems to appear somewhere else. These people are called accountants.
Source, channel and secrecy coding
Coding theory, like Gaul, is lowest rate copy of acrobat 9 pro divided into three parts, called source coding, channel coding and lowest rate copy of acrobat 9 pro secrecy coding.
Source coding
First I’ll tell you lowest rate copy of acrobat 9 pro about source coding. Source coding is what Alice uses to save money on her telephone bills. It is lowest rate copy of acrobat 9 pro usually used for data compression, in other words, to make messages shorter.
There is lowest rate copy of acrobat 9 pro a story about a student of information theory on his first day at college. He had lowest rate copy of acrobat 9 pro entered a strange, bizarre world. The only sounds were the occasional calling out of a lowest rate copy of acrobat 9 pro number by one of the professors, followed by laughter. One professor would say ‘52′, there would be lowest rate copy of acrobat 9 pro a short pause then peals of laughter. Someone else says ‘713′, same thing, everyone falls down laughing.
“What’s going on here?” he asked his tutor.
“We’re telling jokes,” said his tutor.
“Telling jokes?”
“Yes, you see, we’ve all worked here so long we know each other’s jokes. There are lowest rate copy of acrobat 9 pro a thousand of them. So, being information theorists we applied data compression. We just assigned them all numbers, 0 through 999. It saves a lowest rate copy of acrobat 9 pro lot of time and effort. Would you like to try? Just say any number 0 to 999…”
He wasn’t fully convinced. But he tried. Very quietly he whispered “477″.
Hardly a murmur.
He looked at his tutor. “What’s wrong?” he said. “Try again,” says the tutor.
So he does. “318″ - same again, not a thing, hardly a murmur.
“Something’s wrong,” he says.
“Well,” says the tutor, “it’s like this - it’s not so much the joke as the way you tell it!”
There is lowest rate copy of acrobat 9 pro a curious sequel to this story. This student eventually succeeded by accident in the lowest rate copy of acrobat 9 pro most dramatic and unexpected way. He called out a number outside the lowest rate copy of acrobat 9 pro range 0 to 999. “Minus 105,” he said.
At first there was stunned amazement, then lowest rate copy of acrobat 9 pro first one professor laughed, then another then another, till they were all rolling about holding their sides.
None of them had heard that one before.
Channel coding
Next we come to lowest rate copy of acrobat 9 pro channel coding. Channel coding is what Alice uses to overcome the lowest rate copy of acrobat 9 pro noise and interference on the line. Most people have a natural instinct for lowest rate copy of acrobat 9 pro channel coding. What they do is to spell out important words. This adds redundancy and lowest rate copy of acrobat 9 pro enables the listener to cross check. If part of the message is lowest rate copy of acrobat 9 pro lost the missing bit can be reconstructed from the remaining part.
Many organizations such as the lowest rate copy of acrobat 9 pro military, the aviation community, the Police and so on use a lowest rate copy of acrobat 9 pro standard phonetic alphabet specially designed for this purpose. It goes Alpha, Bravo, Charlie, Delta, Echo, Foxtrot, etc. So one says “Mike” and “November”, which is much clearer than saying “M” and “N” which are easily confused otherwise.
Alice uses this lowest rate copy of acrobat 9 pro to explain to Bob that her husband Michael is getting suspicious of her stock option dealing.
“I have to tell you about Mike,” she says. But Bob hears “I XXve to tell u XXt Xxike”.
“What’s that again?” says Bob. “I have to tell you about Mike,” says Alice.
“Didn’t get the last word Alice,” says Bob, “can you spell it out?”
“Mike India Kilo Echo” says Alice.
“Got India Kilo Echo, what was the first word?” says Bob.
“Mike”
“Can you spell that?”
“Mike India Kilo Echo” etc.
Actually there have lowest rate copy of acrobat 9 pro been lots of other phonetic alphabets. The predecessor to the International Phonetic Alphabet went Able, Baker, Charlie…
Then there are lowest rate copy of acrobat 9 pro those based on names of countries:- Africa, Brazil, Chile, Denmark, England, France, Greenland, Holland, India, Japan, Khazakistan, Lithuania, Morocco, Niger, Oman, Papua, Qatar, Russia, Spain, Tanzania, Uruguay, Venezuela, Westphalia, Yemen, Xanadu, Zambia.
My personal favorite is this:
A for ‘Orses
B for Mutton
C for Yourself
D for Mation
E for Brick
F for Vescence /* EFFERVESCENCEdo you get it? do you get ALL of it? :)) -Luan */
G for Police
H for Consent
I for Lutin
J for Orange
K for Teria
L for Leather
M for Sis
N for Mation
O for A Muse of Fire
P for Ate
Q for A Song
S for Something Else
T for Two
U for Mism
V for La France
W for Mism
X for Breakfast
Y for Lover
Z (zee) for yourself
Secrecy coding
Finally we come to lowest rate copy of acrobat 9 pro Secrecy Coding, or Cryptography. Secrecy Coding is what Alice uses to lowest rate copy of acrobat 9 pro try to stop the tax authorities and the secret police understanding her telephone conversations.
Now cryptographers are lowest rate copy of acrobat 9 pro very peculiar people. They have very devious minds. Sometimes they encrypt jokes. Security agencies call these “Covert Jokes”. People who make them are CryptoLaffers.
An intelligible joke in its raw form is lowest rate copy of acrobat 9 pro called the Plainjoke, and after encryption is called the Cipherjoke or lowest rate copy of acrobat 9 pro Cryptojoke. Cipherjokes are intelligible of course only after Decryption, or as some people call it, after explanation.
There are lowest rate copy of acrobat 9 pro three kinds of attack on an unintelligible cryptojoke according to lowest rate copy of acrobat 9 pro the Jokeanalyst’s resources. Firstly there is lowest rate copy of acrobat 9 pro the Cipherjoke-only attack in which the Jokeanalyst is assumed to have lowest rate copy of acrobat 9 pro unlimited amounts of material which is alleged to be funny.
Secondly and lowest rate copy of acrobat 9 pro more powerfully there is the Known Plainjoke Attack in which he is lowest rate copy of acrobat 9 pro given examples of jokes together with their explanations.
But most powerful of all is lowest rate copy of acrobat 9 pro the Chosen Plainjoke Attack where he gets to ask the lowest rate copy of acrobat 9 pro Cryptolaffer to explain WHY the joke is funny.
Feeble jokes are lowest rate copy of acrobat 9 pro usually encrypted using only a very simple cipher, like changing the lowest rate copy of acrobat 9 pro punch line. This is called the DEFLECTED ENDING SYSTEM or DES.
Very good jokes, the lowest rate copy of acrobat 9 pro comprehension of which by outsiders could constitute a threat to lowest rate copy of acrobat 9 pro national security, are encrypted much more securely, usually by completely changing the lowest rate copy of acrobat 9 pro scenario, the plot and the conclusion. This is the PARTICULARLY KLEVER COVERUP or lowest rate copy of acrobat 9 pro PKC. The best known PKC RESISTS SERIOUS ATTACK and is lowest rate copy of acrobat 9 pro therefore called the RSA.
As a lowest rate copy of acrobat 9 pro corollary of course, it follows that only very gifted, intelligent people can lowest rate copy of acrobat 9 pro truly appreciate a funny speech.
Standardisation
Since it lowest rate copy of acrobat 9 pro is difficult to design a good cipher, and since the apparatus is lowest rate copy of acrobat 9 pro very expensive, a lot of work has been done recently to lowest rate copy of acrobat 9 pro try to standardize on them. Even as I speak the International Standards Organization is lowest rate copy of acrobat 9 pro meeting to decide on this very issue. Since there is a lowest rate copy of acrobat 9 pro lot of confusion on this point I have been asked to lowest rate copy of acrobat 9 pro make the position clear. The purpose of language is to convey information. This only works if both sender and lowest rate copy of acrobat 9 pro receiver of information both use the same system. In other words language only works precisely because it lowest rate copy of acrobat 9 pro is standardized.
The purpose of cryptography on the lowest rate copy of acrobat 9 pro other hand is to make the message unintelligible except to one person. In other words cryptography only works precisely because it lowest rate copy of acrobat 9 pro is NOT standardized.So what they do is to make most of the lowest rate copy of acrobat 9 pro cipher standardized, and to concentrate the non-standardization into one part called the lowest rate copy of acrobat 9 pro key.
So far so good. But of course the lowest rate copy of acrobat 9 pro key, the non-standardized part, must be nonstandard in only standardized ways. And also key management must conform to lowest rate copy of acrobat 9 pro certain standards. In other words standards are being formulated whereby the lowest rate copy of acrobat 9 pro nonstandard parts, which must conform to certain standards of non-standardization, are lowest rate copy of acrobat 9 pro also to be handled only in a standardized nonstandard way in order to lowest rate copy of acrobat 9 pro standardize on the overall non-standardization.
I hope this makes the position clear.
Weak keys
Many ciphers have lowest rate copy of acrobat 9 pro certain bad keys. If you use one of them the cipher is lowest rate copy of acrobat 9 pro easily broken. For instance all-zeros is a weak key for the lowest rate copy of acrobat 9 pro DES. There has been a lot of research done into searching for lowest rate copy of acrobat 9 pro weak keys. Over the years more and more weak keys have lowest rate copy of acrobat 9 pro been found till now one has to be quite careful to lowest rate copy of acrobat 9 pro avoid them.
Perhaps it lowest rate copy of acrobat 9 pro would be a better idea if we looked for strong keys. In fact, why not look for lowest rate copy of acrobat 9 pro THE STRONGEST POSSIBLE KEY.
Then we could all standardize on it.
Processing delay
Coding theory is lowest rate copy of acrobat 9 pro not without its problems. The introduction of source coding, channel coding and lowest rate copy of acrobat 9 pro secrecy coding often introduces something called PROCESSING DELAY. This is the lowest rate copy of acrobat 9 pro delay caused by the time it takes to do all this lowest rate copy of acrobat 9 pro coding and decoding. These delays can be enormous.
History gives us instances when lowest rate copy of acrobat 9 pro this delay has changed the course of world events. There is lowest rate copy of acrobat 9 pro a recorded case of a two-word military signal which suffered a lowest rate copy of acrobat 9 pro processing delay of 150 years. The message, deciphered at the Pentagon in 1972, simply read “Send Reinforcements”. It was sent on 1830 from Little Bighorn by General Custer.
Consider the message: “Return home at once, trip cancelled.” and lowest rate copy of acrobat 9 pro think of the effect on world events if it had lowest rate copy of acrobat 9 pro been decoded in time. It was sent in 1492 by Isobella of Spain to lowest rate copy of acrobat 9 pro Christopher Columbus.
But these delays are lowest rate copy of acrobat 9 pro nothing in comparison with the next example. We are told by Suetonius that lowest rate copy of acrobat 9 pro Julius Caesar communicated with the Orator Cicero in a cipher in which ‘A’ was sent as ‘B’, ‘B’ as ‘C’ and lowest rate copy of acrobat 9 pro so on. If you apply this cipher to HAL - the lowest rate copy of acrobat 9 pro computer in the Stanley Kubrick movie: 2001 - you get IBM. Some correspondence from lowest rate copy of acrobat 9 pro Julius Caesar to Cicero in this complex cipher have finally been lowest rate copy of acrobat 9 pro deciphered by GCHQ and will be published in the June edition of Cryptologia. Their contents paint a lowest rate copy of acrobat 9 pro disturbingly different picture of the world from Caesar’s official dispatches to Rome in De Bello Gallico.
I am lowest rate copy of acrobat 9 pro privileged to have an advance copy, from which I will read you lowest rate copy of acrobat 9 pro an extract.
“Alexandria, April 14th 48 BC (think about it)
Dear Marcus Tullius
Thank the lowest rate copy of acrobat 9 pro Gods you and I have a secure cipher. I would not care to lowest rate copy of acrobat 9 pro have our messages read by my enemies. Frankly I don’t trust most of the Senate.
Take Mark Anthony. Would you trust him? He’s so incompetent he couldn’t organize a libation at an orgy.
Take Gaius Brutus. Would you buy a used chariot from this man? I think he’s plotting behind my back. Sometimes he scares the lowest rate copy of acrobat 9 pro toga off me.
And as for lowest rate copy of acrobat 9 pro the Gauls. What a bunch of morons. I thought all their problems would be lowest rate copy of acrobat 9 pro solved when we formed the GEC -the Gallic Economic Community. But what lowest rate copy of acrobat 9 pro happens? We guarantee minimum prices on food exports, the so called “Green Denarius”. We provide subsidies on cheap labor saving gadgets - like slaves. Then what lowest rate copy of acrobat 9 pro happens? We get a lowest rate copy of acrobat 9 pro run on the Denarius. Inflation runs at record levels. And they squander our subsidies on gross overproduction of wine. We have lowest rate copy of acrobat 9 pro to sell it off cheap to the Barbarians to maintain the lowest rate copy of acrobat 9 pro price level within the GEC.
I’m fed up with the whole business. When I get back to Rome I’ll retire. I have lowest rate copy of acrobat 9 pro it all planned. I lied about the size of Gaul in my official dispatches. I’ve found the lowest rate copy of acrobat 9 pro most divine little spot for my retirement which I’m keeping quiet about. I’m not having those Senators getting their grubby hands on it. And I’ve taken steps to lowest rate copy of acrobat 9 pro make sure they never can. So for your ears alone Marcus Tullius, I have lowest rate copy of acrobat 9 pro my special, secret retirement place all organized. It doesn’t appear on any map because I authorize the maps.
Officially it doesn’t exist. So it can’t be found or taxed. I’ve managed to conceal a whole extra part of Gaul!
So forget De Bello Gallico. The reality is lowest rate copy of acrobat 9 pro Gaul is divided into FOUR parts.”
The modern world
Well that lowest rate copy of acrobat 9 pro ends the instant course on coding theory. I would like to lowest rate copy of acrobat 9 pro finish with a few words on the impact that information technology is lowest rate copy of acrobat 9 pro having on our everyday lives.
Science has lowest rate copy of acrobat 9 pro marched ahead so fast that we take for granted the most incredible technological developments. Magnetrons, which were a lowest rate copy of acrobat 9 pro closely guarded secret during the 1939-45 war are now part of every microwave cooker. And made in Japan. When I was a lowest rate copy of acrobat 9 pro child, space travel was science fiction. Yet today, advance is so rapid that lowest rate copy of acrobat 9 pro even the astronauts who set foot on the moon in 1969 had lowest rate copy of acrobat 9 pro never seen a digital watch. Nor a pocket calculator.
Pocket calculators! Now there’s something. They’re so complicated! I have lowest rate copy of acrobat 9 pro a calculator which has sines, cosines, tangents, logarithms, hyperbolic functions and lowest rate copy of acrobat 9 pro multiple nested parentheses. You can program it in Fortran, Algol, Basic, Pascal, Forth, Fifth and lowest rate copy of acrobat 9 pro Sixth, ADA and Carruthers. It will factorize primes for you. At present it’s working on the Halting Problem.
It translates from lowest rate copy of acrobat 9 pro one language to another. From German to Spanish. From Macedonian to lowest rate copy of acrobat 9 pro Esperanto. From Cantonese to Greek. Or from American to English.
It is, in fact, a lowest rate copy of acrobat 9 pro multiprocessor system. There are 22 Transputers in there. Sometimes they organize a lowest rate copy of acrobat 9 pro game of football between them.
It has lowest rate copy of acrobat 9 pro a full color, wraparound wide screen, liquid crystal, three-dimensional holographic display. It’s called HoloChromaCinePhotoRamaScope.
Its audio facilities include Dolby Digital Decaphonic surround sound. On the lowest rate copy of acrobat 9 pro way here I watched “The Labyrinth” on it.
It also has lowest rate copy of acrobat 9 pro synthetic speech and a voice recognition system. I often talk to lowest rate copy of acrobat 9 pro it. I tell it my problems. Sometimes it psychoanalyses me. It has lowest rate copy of acrobat 9 pro me figured as paranoid. But that’s just because it keeps getting at me. But don’t get me wrong - it lowest rate copy of acrobat 9 pro can be very user friendly. In fact you can program precisely HOW user friendly you lowest rate copy of acrobat 9 pro want it is to be on a scale from ONE to lowest rate copy of acrobat 9 pro TEN.
On a setting of ONE it won’t even interrupt a lowest rate copy of acrobat 9 pro football game to answer you. But on a setting of TEN it’s so friendly that on a cold day it pre-heats its pushbuttons.
But no matter who smart it SEEMS, deep down inside it’s just a dumb old computer.
One time I got really mad at it. Like all computers, it lowest rate copy of acrobat 9 pro knew precisely what I wanted it to do. It knew exactly what lowest rate copy of acrobat 9 pro I MEANT. So why does it have to go and DO what lowest rate copy of acrobat 9 pro I SAID?
How do you get even with a dumb machine like that?
First I tried slapping it lowest rate copy of acrobat 9 pro around a little. I pushed its buttons a bit hard. I threatened it. “How would you like a busted display” I said.
But it did no good. It just said “I am virtually unbreakable - and I’m not going to lowest rate copy of acrobat 9 pro take any notice till you enter the data nicely, like you lowest rate copy of acrobat 9 pro used to do.”
Whatever I did it always seemed to win.
I decided to lowest rate copy of acrobat 9 pro have a man-to-man talk with it. So I sat it down and lowest rate copy of acrobat 9 pro said to it “Who’s the boss here, you or me?”
No reply.
Again I ask “Who’s the boss, you or me? Go on, answer me!”
“I’m thinking, I’m thinking,” it said.
So I hit it. Hard. Too hard. I cracked its case.
At first I thought that lowest rate copy of acrobat 9 pro was the limit of the damage. But then little things started to lowest rate copy of acrobat 9 pro go wrong. At first there was nothing definite. Nothing you could put your lowest rate copy of acrobat 9 pro finger on. Just little things like stuttering. It just didn’t sound quite the lowest rate copy of acrobat 9 pro same. Its voice seemed to lack its former confidence.
Then once I caught it lowest rate copy of acrobat 9 pro making an arithmetic mistake. Of course I didn’t mention it. But you lowest rate copy of acrobat 9 pro could tell it knew. Its self image was shot to pieces.
Saddest of all, it lowest rate copy of acrobat 9 pro forgot our anniversary - of the day I bought it. In the lowest rate copy of acrobat 9 pro past this had been a special time for us.
I just couldn’t bear it lowest rate copy of acrobat 9 pro any longer. One evening I tucked it up snugly in its case, lit candles, played a lowest rate copy of acrobat 9 pro record which was popular when we first met, and sat down beside it.
“Where did we go wrong?” I said. But it had it pride. It wasn’t about to weaken in front of a non-machine.
“Wrong? Nothing is wrong,” it said. “Just insufficient data.”
But underneath you could tell it was hurt.
From there it was a rapid downhill slide.
Now it lowest rate copy of acrobat 9 pro just mutters to itself. It can only do very simple calculations on small numbers.
Finally came the lowest rate copy of acrobat 9 pro ultimate indignity. It lost control. It leaked electrolyte all over its case.
I felt so bad about it. My other gadgets weren’t happy about it lowest rate copy of acrobat 9 pro either. They all came out in sympathy for the calculator. My watch gave me a lowest rate copy of acrobat 9 pro bad time. My power tools keep blowing fuses.
Then one night last week I was driving my car back from lowest rate copy of acrobat 9 pro London when suddenly the engine stopped all by itself on this lowest rate copy of acrobat 9 pro lonely country road.
I tried to lowest rate copy of acrobat 9 pro get out but the solenoids were inhibited by the central locking computer. Suddenly the lowest rate copy of acrobat 9 pro air conditioner came on and started to blow out freezing cold air. It made a lowest rate copy of acrobat 9 pro noise like wind whistling through the trees. Then this creepy music came from lowest rate copy of acrobat 9 pro the loudspeaker. The sort of music they play in movies when lowest rate copy of acrobat 9 pro the hero is lost in a dark forest.
I got scared. The cold, the lowest rate copy of acrobat 9 pro wind and the weird music got to me. Then it started to lowest rate copy of acrobat 9 pro speak.
“You’re the guy who beats up pocket calculators!”
