Have you seen any of the AdSense image ads? By now, I am sure you have seen a few. The ones you might see most often at SEO/SEM related sites are from Did-It.com. But have you seen the Google Ads within the AdSense network? They basically come up 99% of the time at DigitalPoint's AdSense & AdWords Forum. It looks like the ad below, oh, I made the ad link to http://services.google.com/marketing/links/US-HA-CMBFIRST/ because that is where it links to, but no AdSense account is being funded by you clicking on the Ad (so Google, please don't cancel my AdSense account :)).
