Using Javascript in the address bar

One easy way to run javascript in your browser is to, simply type:

javascript: and then a javascript function

So for example, if you want to change the term Christian Business into scams, just paste this into your address bar.

javascript: document.write(document.childNodes[1].innerHTML.replace(new RegExp(/Christian Business/gi), "scams").replace(new RegExp(/Christian Business/gi), "scams"))

To test this you could go here: http://www.google.com/search?hl=en&q=%22Christian+Business%22&aq=f&aqi=g10&aql=&oq=

And then just paste said javascript into the browser bar.
