jQuery: Getting the two last list items?

Question

I want to apply a special class to the two last list items in an unordered list with jQuery. Like this:

<ul>
<li>Lorem</li>
<li>ipsum</li>
<li>dolor</li>
<li class="special">sit</li>
<li class="special">amet</li>
</ul>

How to? Should I use :eq somehow?

Thanks in advance

Answer 1

var items = $('ul li')
var last_two = items.filter('li:gt('+ items.length-3 +')')
last_two.addClass('special');

Answer 2

$(function(){

  $("li:gt("+($("li").length-3)+")").addClass("special");

});

Answer 3

Another approach, using andSelf and prev:

$('ul li:last-child').prev('li').andSelf().addClass("special");
