selecting spans in a div

selecting spans in a div

Being relatively new to javascript/jquery I cannot figure out why the following code does not work. I am reading through a tutorial and this is holding me up. I am trying to select all spans with a class of title summary in the div id main. Below I included just one episode but there are usually 14 or so.

My code:
$(document).ready(function() {
  $episodes=$("#main .title summary");
  var oner=$episodes.get(0);
  alert($episodes.get(0));
});


The html:
<div id="main">
   <dl class="aired vevent">
      <dt title="Click to view this episode's details" class="odd no-js">
         <span class="nr">1</span>
         <span class="seen">&nbsp;</span>
         <span class="title summary">Pilot</span>
         <span class="ratings s0">
            <span class="one"><a class="ajax_rate" href="/rate/episode/burnnotice/1/1/1/" title="1 Star">1</a></span>
            <span class="two"><a class="ajax_rate" href="/rate/episode/burnnotice/1/1/2/" title="2 Stars">2</a></span>
            <span class="three"><a class="ajax_rate" href="/rate/episode/burnnotice/1/1/3/" title="3 Stars">3</a></span>
            <span class="four"><a class="ajax_rate" href="/rate/episode/burnnotice/1/1/4/" title="4 Stars">4</a></span>
            <span class="five"><a class="ajax_rate" href="/rate/episode/burnnotice/1/1/5/" title="5 Stars">5</a></span>
         </span>
         <span class="nosubs">&nbsp;</span>
      </dt>
      <dd class="ep">
