You don't need to be a uber hacker to do this, heck, you don't even need to know much about computers either. All you need is one line of code, approximately 61 bytes, that's it. I honestly don't know why or how this works, but it works nonetheless.

The code is:

If you want to test it out, click here. But please note that if you are using Internet Explorer, your browser will crash, and it will also take with it all your other windows and or tabs.

If you are using Firefox, or anything other than IE, don't worry, you won't be affected.

If your still using IE, consider this a friendly hint ;)
