You don't want to do this if you are signed up with google adsense

Some things not to do with Google Adsense :

Don't ever click on the ad displayed on your own site even if you
are interested about the content. What you can do is enter the
address of the website given in ad into the search bar manually.

Do not click on your own ads even if you are on someone else's
computer ( may be your friend's, or in college or office ). Google
records the IP of all the page views and ad clicks. Google will
find out that the clicks are coming from the same geographical
location.

Don't sign-up for programs like click exchange. Google will kick
you out.

Don't ask anyone to click on your ads. He might click on your
ads more times from the same IP, resulting in your account
cancellation.

Don't use sneaky redirects or hidden-text links on your site.

Don't write anything on your site encouraging visitors to click on
your ads.

Don't modify the adsense ad code in any way.

Don't publish competitor's ad on the website.

DO NOT LOGIN into Your Adsense Account on a Public PC where other people might click your ads!!

TAKE THIS VERY SERIOUSLY INDEED people get banned from Adsense every day!!
