Don't you love google?

Google Referrals - Here you make money by referring visitors to use a Google product, like AdSense, AdWords, the Google Toolbar and other Google software. Just like Google AdSense for Content and AdSense for Search, Google generates the code that you paste into the desired location on your web page. You can choose from a wide variety of buttons and text links of different colors. As an example of how Google Referrals works, if someone goes to your site and clicks the link and signs up for an AdSense account, when that person earns a $100 from Google AdSense and receives a payout from Google, you'll also receive $100 for referring them. This is a great idea to me, because you can be the world's worst Google AdSense advertiser, but if an ad dynamo happens to visit your site and uses your referral link, you can make money anyway!
