title: Jquery append vs appendTo
body: <p>Can someone explain why I can append a string to a <code>&lt;p&gt;</code> tag but I cannot appendTo. This is my code</p>
  <pre><code>$('#append').click(function(){
    $('p:first').append('hello');
  });
  
  $('#appendTo').click(function(){
   $('hello').appendTo('p:first');
  });
  </code></pre>
