Luckily most adults aren’t silly enough to believe in Santa Claus. It’s a little cruel to subject kids to it, but I had no problem with it growing up. I kinda liked the guy. He was always generous with us.
I got this in my email, without any copyright and barely any attribution, so I’ll post it here pretty much as I received it – though I added a few illuminating links – and hope I’m not stepping on too many toes. I always like to see logical explanations disproving silly things; it’s too bad the arguments against god(s) aren’t this ridiculously easy and amusing:

Subject: The physics of Santa Claus (do not read if you believe in Santa)
To:
1. No known species of reindeer can fly. BUT there are 300,000 species of
living organisms yet to be classified, and while most of these are insects
and germs, this does not COMPLETELY rule out flying reindeer, which only
Santa has ever seen.
2. There are 2 billion children (persons under 18) in the world. BUT since
Santa doesn’t (appear) to handle the Muslim, Hindu, Jewish and Buddhist
children, that reduces the workload to 15% of the total – 378 million
according to the Population Reference Bureau. At an average (census rate of
3.5 children per household, that’s 91.8 million homes. One presumes there’s
at least one good child in each.
3. Santa has 31 hours of Christmas to work with, thanks to the different
time zones and the rotation of the earth, and assuming he travels east to
west (which seems logical). This works out to 822.6 visits per second. This
is to say that for each Christian household with good children, Santa has
1/1000th of a second to park, hop out of his sleigh, jump down the chimney,
fill the stockings, distribute the remaining presents under the tree, eat
whatever snacks have been left, get back up the chimney, get back into the
sleigh and move on to the next house. Assuming that each of these 91.8
million stops are evenly distributed around the earth (which, of course we
know to be false but for the purpose of our calculations we will accept), we
are now talking about .78 miles per household, a total trip of 75.5 million
miles, not counting stops to do what most of us must do at least once every
“,0] ); //–>31 hours, plus feeding, etc.This means that Santa’s sleigh is moving at 650
miles per second, 3000 times the speed of sound. For purposes of comparison,
the fastest man-made vehicle on earth, the Ulysses space probe, moves at a
poky 27.4 miles per second – a conventional reindeer can run, tops, 15 miles
per hour.
4. The payload on the sleigh adds another interesting element. Assuming that
each child gets nothing more than a medium-sized lego set (2 pounds), the
sleigh is carrying 321,300 tons, not counting Santa, who is invariably
described as overweight. On land, conventional reindeer can pull no more
than 300 ponds. Even granting that “flying reindeer” (refer to point #1)
could pull TEN TIMES the normal load, we cannot do the job with eight, or
even nine. We need 214,200 reindeer. This increases the payload – not even
counting the weight of the sleigh – 353,430 tons. Again, for comparison -
this is four times the weight of the Queen Elizabeth.
353,000 tons traveling at 650 miles per second creates enormous air
resistance – this will heat the reindeer up in the same fashion as
spacecrafts re-entering the earth’s atmosphere. The lead pair of reindeer
will absorb 14.3 QUINTILLION joules of energy per SECOND, EACH! In short,
they will burst into flames almost instantaneously, exposing the reindeer
behind them, and create a deafening sonic boom in their wake. The entire
reindeer team will be vaporized within 4.26 thousandths of a second. Santa,
meanwhile, will be subjected to centrifugal* forces 17,500.06 times greater
than gravity. A 250 pound Santa (which seems ludicrously slim) would be
pinned to the back of his sleigh by 4 billion pounds of force.
In conclusion – If Santa ever DID deliver presents on Christmas Eve, he’s
star dust by now.
*Please note that centrifugal is a made-up non existent word. The real word
should be centripetal. Centrifugal is a made up force that physics people
HATE! So please, everyone use the world centripetal, not centrifugal.
Thanks!

I’d never heard such invective against centrifugality. Of course, I’m not a physicist, nor am I a physician. But then, look here:
