how should i protect my arduino from static electricity?

 I currently have an arduino mega and have nothing to protect it from a static shock. At the very least give me advice on how to prevent me from building up static electricity

Drench it with Static Guard spray.

Seriously, though, this depends on the application.  If you don't intend to take it apart, you could always use something metal (such as an Altoids tin) to make a shield and solder it to ground - provided there's enough room that it won't hit any components.

Particularly in the winter, static is a big problem due to the dry air.  Use a humidifier once in awhile or boil some water and make a cup of tea right before working with it.  Invest in an anti-static wrist strap and connect yourself to ground.

Oh, and don't pet a cat while wearing an angora sweater and work on your Arduino at the same time.

I've never personally known any computer component to be damaged by static electricity.
If you're worried, have the thing earthed via the 0V GND line and encase it in a metal box connected to GND also.
Don't shuffle on a nylon carpet, don't wear 100% synthetic clothes, don't rub balloons on yourself, touch an earth connection before opening the thing up.

Up here, in our climate,  static zapping is unlikely to say the least.

You saw this? Electronics aren't always as fragile as people think.

Ideally you would be wearing an anti-static wristband or anti-static gloves when handling it.  The gloves I don't see in the stores too often (and some of the ones I've found may not actually even work), and the wristbands rely on you having a way to ground them. 

Arduino's are pretty hardy creatures and I haven't heard of anyone having a static-related problem with them.  I've played with similar processors while wearing a fleece sweater and wool socks on a carpeted floor at a plastic table with no damage.  I think it would take a lot of repeated jolts or one really really big one to harm it, so unless you're having to deal with a lot of static in your home, I wouldn't worry.

Anyway if you do think you might have a static problem in your home, there are a couple things you might want to do:
-Don't work with it on a plastic table, carpet, or your bed.
-Try to ground yourself before working on it.  If you have a desktop computer, just try to find some bare metal on the back of it and touch that. 
-Wear an anti-static strap.  You can buy one of these cheaply on ebay, or find one anywhere that sells computer parts.
-Raise the humidity a little bit.  If you don't have or want to buy a humidifier, just set a bowl of water out in the room you're working in and change it every few days.
