The Fat King

Once upon a time there was a kingdom with... a fat king! He was very fat and lazy, he had 10 servants to help him to eat, and helped him to go to bed, and lots of other things. His first servant served the food on the table, the second servant put food on the spoon, the third servant opened his mouth, the fourth servant put the food in his mouth, the fifth servant had to help him chew! The sixth one fed him soup, the seventh one blew the soup if it was too hot, the eighth one wiped his mouth with a wet towel, the ninth one fed him desserts, and the tenth one put drinks in his mouth.

### You can find your Wireless Network Key on Virgin Media Wireless Router

We have a new netbook computer, and don't know where to find network key, which is needed to setup wireless connection.

A network key may also be called WEP (Wired Equivalent Privacy) key or WPA (Wi-Fi Protected Access) key.

A wireless network key is a security feature that prevents unauthorized users from accessing a wireless network. An unprotected network is an unlocked virtual door, anybody within range can piggyback on the network undetected.

I use Virgin media broadband with a Virgin media wireless router, this router has a WPA key taped on the router, that WPA key is an English word consisting of 10 letters.

To tape network key on the router is a good idea, because we may never lose or forget a wireless network key as long as we possess the router.

The surcoat was the loose garment worn over the armour to protect it from rain or hot sun and actually was the "coat-of-arms"; it was decorated on the front and back with the same device as on the shield.
The correct expression for entire design is an achievement. An achievement consists of the shield, helmet, rest, wreath, mantling and motto. These are the main parts. To them can be added supporters and a compartment.

In the centre is the most important part, the shield. The surface of the shield is called the field and on it the colourful charges are placed. The shield is called the arms or coat-of-arms and can be drawn in any shape - in an upright position or slanting, which is the position it would fall into if hung on a peg. In Heraldry it slants to dexter.

The helmet denotes the ran…
