If you are a window user, this could be something interesting to play with. For killing abit of your time.
*~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~*
Magic 1
=======
An Indian discovered that nobody can create a FOLDER anywhere on the computer named as "CON". No one from Microsoft can answer why this happened!

TRY IT NOW, and see for yourself. IT WILL NOT CREATE "CON" FOLDER

Magic 2
=======
Do the following:

1.) Open an empty notepad file
2.) Type "Bush hid the facts" (without the quotes)
3.) Save it as whatever you want.
4.) Close it, and re-open it. Is it just a really weird bug?

Magic 3
=======
It was discovered by a Brazilian.

Open Microsoft Word and type

=rand (200, 99)

And then press ENTER

Then see what happened....

*Note* - these "magic" do no harm to your computer, I had tried out myself! And my window still as healthy as usual.
