Here is the code for one of the links on the MSN home page:

Code:
<a style="background: rgb(26, 118, 183) none repeat scroll 0%; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial;" notrack="1" title="Blue theme" id="Dblu" href="http://stc.msn.com/br/hp/en-us/css/38/blu.css"></a>
Notice all the Mozilla specific tags? I found that amusing. If they would just stick to web standards, they wouldn't need to hack their own page.
