I. There are approximately two billion children (persons under 18) in the world. However, since Santa does not visit children of Muslim, Hindu, Jewish or Buddhist religions, this reduces the workload for Christmas night to 15% of the total, or 378 million (according to the Population Reference Bureau).
At an average (census) rate of 3.5 children per house hold, that comes to 108 million homes, presuming that there is at least one good child in each.
II. Santa has about 31 hours of Christmas to work with, thanks to the different time zones and the rotation of the earth, assuming he travels east to west (which seems logical). This works out to 967.7 visits per second. This is to say that for each Christian household with a good child, Santa has around 1/1000th of a second to park the sleigh, hop out, jump down the chimney, fill the stockings, distribute the remaining presents under the tree, eat whatever snacks have been left for him, get back up the chimney, jump into the sleigh and get on to the next house.
Assuming that each of these 108 million stops is evenly distributed around the earth (which, of course, we know to be false, but will accept for the purposes of our calculations), we are now talking about 0.78 miles per household; a total trip of 75.5 million miles, not counting bathroom stops or breaks. This means Santa's sleigh is moving at 650 miles per second --- 3,000 times the speed of sound. For purposes of comparison, the fastest man-made vehicle, the Ulysses space probe, moves at a poky 27.4 miles per second, and a conventional reindeer can run (at best) 15 miles per hour.
III. The payload of the sleigh adds another interesting element. Assuming that each child gets nothing more than a medium sized Lego set (two pounds), the sleigh is carrying over 500 thousand tons, not counting Santa himself. On land, a conventional reindeer can pull no more than 300 pounds. Even granting that the "flying" reindeer could pull ten times the normal amount, the job can't be done with eight or even nine of them--- Santa would need 360,000 of them. This increases the payload, not counting the weight of the sleigh, another 54,000 tons, or roughly seven times the weight of the Queen Elizabeth (the ship, not the monarch).
IV. 600,000 tons traveling at 650 miles per second creates enormous air resistance --- this would heat up the reindeer in the same fashion as a spacecraft re-entering the earth's atmosphere. The lead pair of reindeer would absorb 14.3 quintillion joules of energy per second each. In short, they would burst into flames almost instantaneously, exposing the reindeer behind them and creating deafening sonic booms in their wake.
The entire reindeer team would be vaporized within 4.26 thousandths of a second, or right about the time Santa reached the fifth house on his trip.
Not that it matters, however, since Santa, as a result of accelerating from a dead stop to 650 m.p.s. in .001 seconds, would be subjected to centrifugal forces of 17,500 g's. A 250 pound Santa (which seems ludicrously slim) would be pinned to the back of the sleigh by 4,315,015 pounds of force, instantly crushing his bones and organs and reducing him to a quivering blob of pink goo.
Therefore, if Santa did exist, he's dead now. |

"At my first year of college my physics teacher told us this rather amusing story, I’ve never forgotten this story - but I certainly have forgotten everything I learned in that class.
The following question was asked at the University of Copenhagen in a physics exam:
“”Describe how to determine the height of a skyscraper with a barometer.”
One student replied:
“You tie a long piece of string to the neck of the barometer, then lower the barometer from the roof of the skyscraper to the ground. The length of the string plus the length of the barometer will equal the height of the building.”
This highly original answer so incensed the examiner that the student was failed immediately. He appealed on the grounds that his answer was indisputably correct, and the university appointed an independent arbiter to decide the case. The arbiter judged that the answer was indeed correct, but did not display any noticeable knowledge of physics. To resolve the problem it was decided to call the student in and allow him six minutes in which to provide a verbal answer which showed at least a minimal familiarity with the basic principles of physics. For five minutes the student sat in silence, forehead creased in thought. The arbiter reminded him that time was running out, to which the student replied that he had several extremely relevant answers, but couldn’t make up his mind which to use. On being advised to hurry up the student replied as follows:
“Firstly, you could take the barometer up to the roof of the skyscraper, drop it over the edge, and measure the time it takes to reach the ground. The height of the building can then be worked out from the formula H = 0.5g x t squared. But bad luck on the barometer.
“Or if the sun is shining you could measure the height of the barometer, then set it on end and measure the length of its shadow. Then you measure the length of the skyscraper’s shadow, and thereafter it is a simple matter of proportional arithmetic to work uut the height of the skyscraper.
“But if you wanted to be highly scientific about it, you could tie a short piece of string to the barometer and swing it like a pendulum, first at ground level and then on the roof of the skyscraper. The height is worked out by the difference in the gravitational restoring force T = 2 pi sqrroot (l/g).
“Or if the skyscraper has an outside emergency staircase, it would be easier to walk up it and mark off the height of the skyscraper in barometer lengths, then add them up.
“If you merely wanted to be boring and orthodox about it, of course, you could use the barometer to measure the air pressure on the roof of the skyscraper and on the ground, and convert the difference in millibars into feet to give the height of the building.
But since we are constantly being exhorted to exercise independence of mind and apply scientific methods, undoubtedly the best way would be to knock on the janitor’s door and say to him ‘If you would like a nice new barometer, I will give you this one if you tell me the height of this skyscraper’.”
The student was Nils Bohr, the first Dane to win the Nobel prize for Physics. “ |

Dr. Schambaugh, of the University of Oklahoma School of Chemical Engineering, Final Exam question for May of 1997. Dr. Schambaugh is known for asking questions such as, "why do airplanes fly?" on his final exams. His one and only final exam question in May 1997 for his Momentum, Heat and Mass Transfer II class was: "Is hell exothermic or endothermic? Support your answer with proof."
Most of the students wrote proofs of their beliefs using Boyle's Law or some variant. One student, however, wrote the following:
"First, We postulate that if souls exist, then they must have some mass. If they do, then a mole of souls can also have a mass. So, at what rate are souls moving into hell and at what rate are souls leaving? I think we can safely assume that once a soul gets to hell, it will not leave.
Therefore, no souls are leaving. As for souls entering hell, let's look at the different religions that exist in the world today. Some of these religions state that if you are not a member of their religion, then you will go to hell. Since there are more than one of these religions and people do not belong to more than one religion, we can project that all people and souls go to hell. With birth and death rates as they are, we can expect the number of souls in hell to increase exponentially.
Now, we look at the rate of change in volume in hell. Boyle's Law states that in order for the temperature and pressure in hell to stay the same, the ratio of the mass of souls and volume needs to stay constant. Two options exist:
1. If hell is expanding at a slower rate than the rate at which souls enter hell, then the temperature and pressure in hell will increase until all hell breaks loose.
2. If hell is expanding at a rate faster than the increase of souls in hell, then the temperature and pressure will drop until hell freezes over.
So which is it? If we accept the quote given to me by Theresa Manyan during Freshman year, "that it will be a cold night in hell before I sleep with you" and take into account the fact that I still have NOT succeeded in having sexual relations with her, then Option 2 cannot be true...Thus, hell is exothermic."
The student, Tim Graham, got the only A. |

A businessman met a beautiful girl and agreed to spend
the night with her for $500. They did their thing,
and, before he left, he told her that he did
not have any cash with him, but he would have his
secretary write a check and mail it to her, calling
the payment 'RENT FOR APARTMENT.'
On the way to the office, he regretted what he had
done, realizing that the whole event had not been
worth the price. So he had his secretary send a check for $250 and enclose the following typed note:
'Dear Madam:
Enclosed find a check for $250 for rent of your
apartment . I am not sending the amount agreed upon,
because when I rented the place, I was under the
impression that:
#1 - it had never been occupied;
#2 - there was plenty of heat; and
#3 - it was small enough to make me feel cozy and at home.
However, I found out that:
#1 - it had been previously occupied,
#2 - there wasn't any heat, and
#3 - it was entirely too large.'
Upon receipt of the note, the girl immediately
returned the check for $250 with the following note:
'Dear Sir:
#1 - I cannot understand how you could expect a
beautiful apartment to remain unoccupied indefinitely.
#2 - As for the heat, there is plenty of it, if you
know how to turn it on.
#3 - Regarding the space, the apartment is indeed of
regular size, but if you don't have enough furniture
to fill it, please do not blame the management.
So, Please send the rent in full or we will be forced
to contact your present landlady...

An 86 year old man walked into a crowded doctor's office.
As he approached the desk, the receptionist said, "Yes sir, what are you seeing the doctor for today?"
"There's something wrong with my penis," he replied.
The receptionist became irritated and said, "You shouldn't come into a crowded office and say things like that."
"Why not? You asked me what was wrong and I told you," he said.
The receptionist replied, "You've obviously caused some embarrassment in this room full of people.You should have said there is something wrong with your ear or something and then discussed the problem further with the doctor in private."
The man walked out, waited several minutes and then re-entered.
The receptionist smiled smugly and asked, "Yes?"
"There's something wrong with my ear," he stated.
The receptionist nodded approvingly and smiled, knowing he had taken her advice. "And what is wrong with your ear, Sir?" "I can't piss out of it," the man replied.
The doctor's office erupted in laughter. |

My job is so fucking unbelievable. I'll try to sum it up by first telling you about the folks I work with:
First, there is this supermodel wanna-be chick. Yeah, okay, she is pretty hot, but damn is she completely useless. The girl is constantly fixing her hair or putting on makeup. She is extremely self-centered and has never once considered the needs or wants of anyone but herself. She is as dumb as a box of rocks, and I still find it surprising that she has enough brain power to continue to breathe.
The next chick is completely the opposite. She might even be one of the smartest people on the planet. Her career opportunities are endless, and yet she is here with us. She is a zero on a scale of 1 to 10. I'm not sure she even showers, much less shaves her "womanly" parts. I think she might be a lesbian, because every time we drive by the hardware store, she moans like a cat in heat.
But the jewel of the crowd has got to be the fucking stoner. And this guy is more than just your average pothead. In fact, he is baked before he comes to work, during work, and I'm sure after work. He probably hasn't been sober anytime in the last ten years, and he's only 22. He dresses like a beatnik throwback from the 1960's, and to make things worse, he brings his big fucking dog to work. Every fucking day I have to look at this huge Great Dane walk around half-stoned from the second-hand smoke. Hell, sometimes I even think it's trying to talk with its constant bellowing. Also, both of them are constantly hungry, requiring multiple stops to McDonalds and Burger King, every single fucking day.
Anyway, I drive these fucktards around in my van and we solve mysteries and shit. |

Dear TIDE,
I am writing to say what an excellent product you have! I've used it all of my married life, as my Mom always told me it was the best.
Now that I am in my fifties I find it even better!About a month ago, I spilled some red wine on my new white blouse. My inconsiderate and uncaring husband started to belittle me about how clumsy I was, and generally started becoming a pain in the neck.
One thing led to another and somehow I ended up with his blood on my new white blouse! I grabbed my bottle of Tide with bleach alternative, and to my surprise and satisfaction, all of the stains came out! In fact, the stains came out so well the detectives who came by yesterday told me that the DNA tests on my blouse were negative and then my attorney called and said that I was no longer considered a suspect in the disappearance of my husband...
What a relief! Going through menopause is bad enough without being a murder suspect! I thank you, once again, for having a great product.Well, I gotta go - I have to write to the Hefty bag people. |

John Smith started the day early, having set his alarm clock (MADE IN JAPAN) for 6 a.m. He got out of bed (MADE IN CHINA) and shaved with his electric razor (MADE IN HONG KONG).
He put on a shirt (MADE IN SRI LANKA), jeans (MADE IN SINGAPORE), and tennis shoes (MADE IN SOUTH KOREA).
After cooking his breakfast in his new electric skillet (MADE IN INDIA), he sat down with his calculator (MADE IN MEXICO) to see how much he could spend today. After setting his watch (MADE IN TAIWAN) to the radio (MADE IN IN INDIA), he got in his car (MADE IN GERMANY), filled it with gas (FROM SAUDI ARABIA) and continued his search for a good paying AMERICAN JOB.
At the end of yet another discouraging and fruitless day checking his computer (MADE IN MALAYSIA), John decided to relax for a while. He put on his sandals (MADE IN BRAZIL) turned on his TV (MADE IN INDONESIA) and then wondered why he can't find a good paying job in AMERICA?

Once upon a time, a perfect man and a perfect woman met.
After a perfect courtship, they had a perfect wedding.
Their life together was, of course, perfect.
One snowy, stormy Christmas Eve, this perfect couple was driving their perfect car along a winding road, when they noticed someone at the side of the road in distress.
Being the perfect couple, they stopped to help.
There stood Santa Claus with a huge bundle of toys.
Not wanting to disappoint any children on the eve of Christmas, the perfect couple loaded Santa and his toys into their vehicle.
Soon they were driving along delivering the toys. Unfortunately, the driving conditions deteriorated and the perfect couple and Santa Claus had an accident.
Only one of them survived the accident.
Question: Who was the survivor?
Answer: The perfect woman survived. She's the only one who really existed in the first place. Everyone knows there is no Santa Claus and there is no such thing as a perfect man!
* Women stop reading here, that is the end of the joke.*
* Men keep reading *
So, if there is no perfect man and no Santa Claus, the woman must have been driving. This explains why there was a car accident.
* Men Keep reading *
By the way, if you're a woman and you're still reading, this illustrates another point: Women never listen! |

A man wakes up one morning to find a bear on his roof. So he looks in the yellow pages and sure enough, there's an ad for "Bear Removers."
He calls the number, and the bear remover says he'll be over in 30 minutes. The bear remover arrives, and gets out of his van. He's got a ladder, a baseball bat, a shotgun and a mean old pit bull.
"What are you going to do," the homeowner asks?
"I'm going to put this ladder up against the roof, then I'm going to go up there and knock the bear off the roof with this baseball bat. When the bear falls off, the pit bull is trained to grab his testicles and not let go. The bear will then be subdued enough for me to put him in the cage in the back of the van."
He hands the shotgun to the homeowner.
"What's the shotgun for?" asks the homeowner.
"If the bear knocks me off the roof, shoot the dog." |

A little old lady is walking down the street dragging two large plastic garbage bags behind her. One of the bags rips, and every once in a while a $20 bill falls out onto the sidewalk.
Noticing this, a policeman stops her, and says, "Ma'am, There are $20 bills falling out of your bag."
"'Oh, really? Darn!" says the little old lady. "I'd better go back, and see if I can find them. Thanks for telling me.."
"Well, now, not so fast," says the cop. "How did you get all that money?' You didn't steal it, did you?"
"Oh, no", says the little old lady. "You see, my back yard is right next to the football stadium parking lot. On game days, a lot of fans come and pee through the fence into my flower garden. So, I stand behind the fence with my hedge clippers. Each time some guy sticks his thing through the fence, I say, '$20 or off it comes."
"Well, that seems only fair." laughs the cop. "OK? Good Luck! Oh, by the way, what's in the other bag?''
"Well, you know", says the little old lady, "not everybody pays." |
