all you need to do is upload the fool.min.js to the /js folder (i put mine is /js/fun/fool.min.js
then edit the PAGE_CONTAINER template and put this line of code before </head>
Code:
<xen:require js="js/fun/fool.min.js" />
<script type="text/javascript">
$(document).ready(function() {
$.fool('wonky');
});
</script>
change 'wonky' to which ever one you want to run. 'wonky' tilts the page off kilter a bit.
