title: Reverse an onClick event
body: <p>I've got this code:</p>
  
  <pre><code>$(function(){
      $('#gallery').click(function(){
          $('.overlay').fadeIn(500);
          $('#infographic').delay(800).fadeIn(200);
      });
  });
  </code></pre>
  
  <p>Now when I click <code>$('#gallery')</code> again, I want the above to reverse. </p>
  
  <p>Anyone??</p>
