My methods are usually a little more intrusive as I tend to simply block IE6 from viewing altogether if it's a low-traffic site.

Here's a more fun and trickier way tho, write this to your document head tag:

<!--[if IE 6]>
<script type="text/javascript">
    /*Load jQuery if not already loaded*/ if(typeof jQuery == 'undefined'){ document.write("<script type=\"text/javascript\"   src=\"http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js\"></"+"script>"); var __noconflict = true; }
    var IE6UPDATE_OPTIONS = {
        icons_path: "http://static.ie6update.com/hosted/ie6update/images/"
    }
</script>
<script type="text/javascript" src="http://static.ie6update.com/hosted/ie6update/ie6update.js"></script>
<![endif]-->

Viewers behind the times will see this:

Script and junk comes from http://ie6update.com/  where you can download the source or just copy the code from the box they provide and leave it hosted with them.

May the cancer end and SOON!
