title: Remove all elements with specific class except for one
body: <p>I have an select list that has multiple values that are equal. I'd like to remove all duplicates and keep one of them.</p>
  
  <pre><code>&lt;select class="pager"&gt;
    &lt;option value="#"&gt;-- Kies een pagina --&lt;/option&gt;
      &lt;option value="some_value" class="active"&gt;1&lt;/option&gt;
      &lt;option value="some_value" class="pager-current"&gt;2&lt;/option&gt;
      &lt;option value="some_value" class="pager-current"&gt;2&lt;/option&gt;
      &lt;option value="some_value" class="pager-current"&gt;2&lt;/option&gt;
      &lt;option value="some_value" class="pager-current"&gt;2&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>So basically I'd like to do</p>
  
  <pre><code>$(select.pager option.pager-current).remove();
  </code></pre>
  
  <p>but keep one <code>option.pager-current</code> element.</p>
  
  <p>Is there an option in jQuery to "Select all except one" element?</p>
