Here are some mathematical facts from me. Since they are related to maths, you can verify them and there is no question of them being wrong.... 
> There are only four numbers (after 1) which are the sums of the cubes of their digits:
153 = 1^3 + 5^3 + 3^3
370 = 3^3 + 7^3 + 0^3
371 = 3^3 + 7^3 + 1^3 and
407 = 4^3 + 0^3 + 7^3
> The sum of any cube when reduced to a single digit will always be either 1, 8, or 9.
For Example:
125 = 1+2+5 =8
729 = 7+2+9 = 18=1+8=9
4913=4+9+1+3=17=1+7=8
64=6+4=10=1+0=1
> The largest number you can write with just 3 digits is 9^(9^9)... Work out the second and third powers first (9*9*9*9*9*9*9*9*9 = 387420489.) We can therefore restate the sum as 9387420489 which works out as.... very very big indeed.
> 111,111,111 x 111,111,111 = 12,345,678,987,654,321
> You may be already knowing this but anyway to Remember value of PI, just count the letters in eash word of the sentence: "May I have a large container of coffee?" Say "Thank you" and you get further decimals of PI [3.141592653...].
> The largest currently known prime number is 2^(230,402,457) ? 1. It has 9,152,052 digits
will post more if you like them.........

Its actually not impossible for people to lick their elbow.
Some people have done it before.(But only a very few).

One thing interesting I have learnt from this thread, other than most 'facts' doing the rounds on emails are not true, is finding the site www.snopes.com
Good site

You could of course cut off your arm above the elbow and then lick it. A bit extreme I know, but the only way a normally proportioned person could do it.moza1 said:

It's one of those sites that you can easily get lost in for more than an hour without relaising how long you've been looking at it. It may not have the flashiest design, but it's a fascinating site.zimrahil said:
Q.: 1) What is the longest word possibly created using only one row on a keyboard?
2) What came first: the match or the lighter?
A.: 1) Typewriter.
2) The cigarette lighter was invented before the match. In 1816, a German chemist named J.W. Dobereiner devised a way of automatically igniting a jet of hydrogen.

Not sure edgarisapimp. BTW there is some interesting facts in this thread
History Lesson
Have a history teacher explain this----- if they can.
Abraham Lincoln was elected to Congress in 1846.
John F. Kennedy was elected to Congress in 1946.
Abraham Lincoln was elected President in 1860.
John F. Kennedy was elected President in 1960.
Both were particularly concerned with civil rights.
Both wives lost their children while living in the White House.
Both Presidents were shot on a Friday.
Both Presidents were shot in the head.
Now it gets really weird.
Lincoln 's secretary was named Kennedy.
Kennedy's Secretary was named Lincoln.
Both were assassinated by Southerners.
Both were succeeded by Southerners named Johnson.
Andrew Johnson, who succeeded Lincoln , was born in 1808.
Lyndon Johnson, who succeeded Kennedy, was born in 1908.
John Wilkes Booth, who assassinated Lincoln, was born in 1839.
Lee Harvey Oswald, who assassinated Kennedy, was born in 1939.
Both assassins were known by their three names.
Both names are composed of fifteen letters.
Now hang on to your seat.
Lincoln was shot at the theater named 'Ford.'
Kennedy was shot in a car called ' Lincoln ' made by 'Ford.'
Lincoln was shot in a theater and his assassin ran and hid in a warehouse.
Kennedy was shot from a warehouse and his assassin ran and hid in a theater.
Booth and Oswald were assassinated before their trials.
And here's the kicker...
A week before Lincoln was shot, he was in Monroe, Maryland
A week before Kennedy was shot, he was with Marilyn Monroe.
Creepy huh?

I'll tell you exactly how a history teacher will explain it. Coincidences. That's all it is. If you look hard enough you can find a series of co-incidences between just about any two people on the planet.
By the way, the last one works better if you say that Kennedy was IN Marilyn Monroe, not with. Besides which, she died more than a year before he was shot.

Predictions that missed the mark
In 1894, the president of the Royal Society, Lord Kelvin, predicted that radio had no future. The first radio factory was opened five years later. He also predicted that heavier-than-air flying machines were impossible. Today, there are more than one billion radio sets in the world, tuned to more than 33 000 radio stations around the world. The Wright Brother's first flight covered a distance equal to only half the length of the wingspan of a Boeing 747.
In the early 20th century a world market for only 4 million automobiles was made because "the world would run out of chauffeurs." Shortly after the end of World War II (1945), the whole of Volkswagen, factory and patents, was offered free to Henry Ford II. He dismissed the Volkswagen Beetle as a bad design. Today, more than 70 million motorcars are produced every year. The Beetle became one of the best-selling vehicles of all time.
The telephone was not widely appreciated for the first 15 years because people did not see a use for it. In fact, in the British parliament it was mentioned there was no need for telephones because "we have enough messengers here." Western Union believed that it could never replace the telegraph. In 1876, an internal memo read: "This telephone has too many shortcomings to be seriously considered as a means of communication." Even Mark Twain, upon being invited by Alexander Graham Bell to invest $5 000 in the new invention, could not see a future in the telephone.
Irish scientist, Dr. Dionysius Lardner (1793 - 1859) didn't believe that trains could contribute much in speedy transport. He wrote: "Rail travel at high speed is not possible, because passengers ' would die of asphyxia' [suffocation]." Today, trains reach speeds of 500 km/h.
In 1943, Thomas Watson, the chairman of IBM forecast a world market for "maybe only five computers." Years before IBM launched the personal computer in 1981, Xerox had already successfully designed and used PCs internally... but decided to concentrate on the production of photocopiers.
In 1894, A.A. Michelson, who with E.W. Morley seven years earlier experimentally demonstrated the constancy of the speed of light, said that the future of science would consist of "adding a few decimal places to the results already obtained."
Perhaps the guy who got it wrong most was the director of the US patent Office: in 1899 he assured President McKinley that "everything that can be invented has already been invented."
To prophesy is extremely difficult - especially with regard to the future. - Chinese proverb
