Several students were asked to prove that all odd integers are prime. The first student to try to do this was a math student. "Hmmm... Well, 1 is prime, 3 is prime, 5 is prime, and by induction, we have that all the odd integers are prime." The second student to try was a man of physics who commented, "I'm not sure of the validity of your proof, but I think I'll try to prove it by experiment." He continues, "Well, 1 is prime, 3 is prime, 5 is prime, 7 is prime, 9 is... uh, 9 is... uh, 9 is an experimental error, 11 is prime, 13 is prime... Well, it seems that you're right." The third student to try it was the engineering student, who responded, "Well, to be honest, actually, I'm not sure of your answer either. Let's see... 1 is prime, 3 is prime, 5 is prime, 7 is prime, 9 is... uh, 9 is... well, if you approximate, 9 is prime, 11 is prime, 13 is prime... Well, it does seem right." Not to be outdone, the computer science student comes along and says "Well, you two sort've got the right idea, but you'll end up taking too long! I've just whipped up a program to REALLY go and prove it." He goes over to his terminal and runs his program. Reading the output on the screen he says, "1 is prime, 1 is prime, 1 is prime, 1 is prime..." | |
Don't get even -- get odd! | |

Every Horse has an Infinite Number of Legs (proof by intimidation): Horses have an even number of legs. Behind they have two legs, and in front they have fore-legs. This makes six legs, which is certainly an odd number of legs for a horse. But the only number that is both even and odd is infinity. Therefore, horses have an infinite number of legs. Now to show this for the general case, suppose that somewhere, there is a horse that has a finite number of legs. But that is a horse of another color, and by the lemma ["All horses are the same color"], that does not exist. | |
jogger, n.: An odd sort of person with a thing for pain. | |
Lemma: All horses are the same color. Proof (by induction): Case n = 1: In a set with only one horse, it is obvious that all horses in that set are the same color. Case n = k: Suppose you have a set of k+1 horses. Pull one of these horses out of the set, so that you have k horses. Suppose that all of these horses are the same color. Now put back the horse that you took out, and pull out a different one. Suppose that all of the k horses now in the set are the same color. Then the set of k+1 horses are all the same color. We have k true => k+1 true; therefore all horses are the same color. Theorem: All horses have an infinite number of legs. Proof (by intimidation): Everyone would agree that all horses have an even number of legs. It is also well-known that horses have forelegs in front and two legs in back. 4 + 2 = 6 legs, which is certainly an odd number of legs for a horse to have! Now the only number that is both even and odd is infinity; therefore all horses have an infinite number of legs. However, suppose that there is a horse somewhere that does not have an infinite number of legs. Well, that would be a horse of a different color; and by the Lemma, it doesn't exist. | |

Proof techniques #2: Proof by Oddity. SAMPLE: To prove that horses have an infinite number of legs. (1) Horses have an even number of legs. (2) They have two legs in back and fore legs in front. (3) This makes a total of six legs, which certainly is an odd number of legs for a horse. (4) But the only number that is both odd and even is infinity. (5) Therefore, horses must have an infinite number of legs.

Blatant assertion Changing all the 2's to _n's Mutual consent Lack of a counterexample, and "It stands to reason" | |
'Naomi, sex at noon taxes.' I moan. Never odd or even. A man, a plan, a canal, Panama. Madam, I'm Adam. Sit on a potato pan, Otis. Sit on Otis. -- The Mad Palindromist | |
That's odd. That's very odd. Wouldn't you say that's very odd? | |
It's odd, and a little unsettling, to reflect upon the fact that English is the only major language in which "I" is capitalized; in many other languages "You" is capitalized and the "i" is lower case. -- Sydney J. Harris | |
There are people who find it odd to eat four or five Chinese meals in a row; in China, I often remind them, there are a billion or so people who find nothing odd about it. -- Calvin Trillin | |
(1) Alexander the Great was a great general. (2) Great generals are forewarned. (3) Forewarned is forearmed. (4) Four is an even number. (5) Four is certainly an odd number of arms for a man to have. (6) The only number that is both even and odd is infinity. Therefore, all horses are black. | |

Once upon a time, when I was training to be a mathematician, a group of us bright young students taking number theory discovered the names of the smaller prime numbers. 2: The Odd Prime -- It's the only even prime, therefore is odd. QED. 3: The True Prime -- Lewis Carroll: "If I tell you 3 times, it's true." 31: The Arbitrary Prime -- Determined by unanimous unvote. We needed an arbitrary prime in case the prof asked for one, and so had an election. 91 received the most votes (well, it *looks* prime) and 3+4i the next most. However, 31 was the only candidate to receive none at all. 41: The Female Prime -- The polynomial X**2 - X + 41 is prime for integer values from 1 to 40. 43: The Male Prime - they form a prime pair. Since the composite numbers are formed from primes, their qualities are derived from those primes. So, for instance, the number 6 is "odd but true", while the powers of 2 are all extremely odd numbers. | |
It hangs down from the chandelier Nobody knows quite what it does Its color is odd and its shape is weird It emits a high-sounding buzz It grows a couple of feet each day and wriggles with sort of a twitch Nobody bugs it 'cause it comes from a visiting uncle who's rich! -- To "It Came Upon A Midnight Clear" | |
The sun was shining on the sea, Shining with all his might: He did his very best to make The billows smooth and bright -- And this was very odd, because it was The middle of the night. -- Lewis Carroll, "Through the Looking Glass" | |
I was in Vegas last week. I was at the roulette table, having a lengthy argument about what I considered an Odd number. -- Steven Wright | |
Linux Infiltrates Windows NT Demo SILICON VALLEY, CA -- Attendees at the Microsoft ActiveDemo Conference held this week in San Jose were greeted by a pleasant surprise yesterday: Linux. Somehow a group of Linux enthusiasts were able to replace a Windows NT box with a Linux box right before the "ActiveDemo" of Windows NT 5 beta. "I have no clue how they were able to pull off this prank," a Microserf spokesman said. "Rest assured, Microsoft will do everything to investigate and prosecute the Linux nuts who did this. Our bottom line must be protected." Bill Gates said, "I was showing off the new features in Windows NT 5 when I noticed something odd about the demo computer. It didn't crash. Plus, the font used on the screen wasn't MS San Serif -- trust me, I know. My suspicions were confirmed when, instead of the "Flying Windows" screensaver, a "Don't Fear the Penguins" screensaver appeared. The audience laughed and applauded for five straight minutes. It was so embarrasing -- even more so than the pie incident. One attendee said, "Wow! This Linux is cool -- it didn't crash once during the entire demo! I'd like to see NT do that." Another asked, "You guys got any Linux CDs? I want one. Forget about vaporware NT." Yet another remarked, "I didn't know it was possible to hack Linux to make it look like NT. I can install Linux on my company's computers without my boss knowing!" | |
"A penny for your thoughts?" "A dollar for your death." -- The Odd Couple | |
There was a college student trying to earn some pocket money by going from house to house offering to do odd jobs. He explained this to a man who answered one door. "How much will you charge to paint my porch?" asked the man. "Forty dollars." "Fine" said the man, and gave the student the paint and brushes. Three hours later the paint-splattered lad knocked on the door again. "All done!", he says, and collects his money. "By the way," the student says, "That's not a Porsche, it's a Ferrari." | |
This planet has -- or rather had -- a problem, which was this: most of the people living on it were unhappy for pretty much of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movements of small green pieces of paper, which is odd because on the whole it wasn't the small green pieces of paper that were unhappy. -- Douglas Adams | |
Odd that we think definitions are definitive. :-) -- Larry Wall in <199702221943.LAA20388@wall.org> | |
But then it's a bit odd to think that declaring something int could actually slow down the program, if it ended up forcing more conversions back to string. -- Larry Wall in <199708040319.UAA16213@wall.org> | |
Do you think the "Monkees" should get gas on odd or even days? | |
A woman went into a hospital one day to give birth. Afterwards, the doctor came to her and said, "I have some... odd news for you." "Is my baby all right?" the woman anxiously asked. "Yes, he is," the doctor replied, "but we don't know how. Your son (we assume) was born with no body. He only has a head." Well, the doctor was correct. The Head was alive and well, though no one knew how. The Head turned out to be fairly normal, ignoring his lack of a body, and lived for some time as typical a life as could be expected under the circumstances. One day, about twenty years after the fateful birth, the woman got a phone call from another doctor. The doctor said, "I have recently perfected an operation. Your son can live a normal life now: we can graft a body onto his head!" The woman, practically weeping with joy, thanked the doctor and hung up. She ran up the stairs saying, "Johnny, Johnny, I have a *wonderful* surprise for you!" "Oh no," cried The Head, "not another HAT!" | |
