I always enjoy watching the different ways people try to integrate adsense into their pages. Google has certain rules for what you can and can’t do, but they don’t seem to care too much. At the end of the day, the more you can make your links look like they are a part of your site and not ads, the better you will do. The “Valentines Day Cards” text below is actually a link, but isn’t underlined - they don’t want the user to click on it (but probably want some defense in case google complains)
