you dont need prototype to do that.

<ul id="yourUL">
<li>Fuck Off</li>
<li>Fuck Off</li>
<li>Fuck Off</li>
<li>Fuck Off</li>
...
</ul>

<script type="text/javascript">
var listElements = document.getElementById('yourUL').getElementsByTagName('li');
for (var i=0;i<listElements.length; i++)
{
   listElements[i].onclick = function ()
   {
       toggleSelection(this);
   }
}
</script>
