I remember the song, I actually liked it. Then
@Arankaaa Yeah probably your copy, and my wife would gang up on me.Nice of you to warn me though..............I agree with you, it is going a lot faster than the lyrics of that song.
A couple had two mischievous little boys, ages eight and 10. At their wits' end, the parents contacted a clergyman who had been successful in rehabilitating bad children in the past.
The clergyman asked to see the boys individually. The eight-year-old was sent to meet with him first. The clergyman sat the boy down and asked him sternly, "Where is God?"
The boy made no response, so the clergyman repeated the question in an even sterner tone, "Where is God?"
Again the boy made no attempt to answer, so the clergyman raised his voice even more and shook his finger in the boy's face, "WHERE IS GOD?"
At that, the boy bolted from the room, ran directly home, and slammed himself in his closet. His older brother followed him into the closet and asked what happened.
The younger brother replied, "We are in big trouble this time. God is missing, and they think we did it!"

Santa Claus: An Engineer's Perspective
* 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 household, that comes to 108 million homes, presuming that there is at least one good child in each.
* 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, hope back into the sleigh, and get 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.
* The payload of the sleigh adds another interesting element. Assuming that each child gets nothing more that 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 Santa, which is reported to be fairly impressive -- to 600,000 tons.
* 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 away, and just before the sleigh, presents, and Santa followed.
* Therefore, if Santa did exist, he's dea
