title: Getting the the value of a Key without know the name of the key
body: <p>I have an object like this:</p>
  
  <pre><code>var foo = { 'bar' : 'baz' }
  </code></pre>
  
  <p><em>bar</em> can be any word, I need to read <em>baz</em>. Since the object is always like this (one row) I find making an each cycle inefficient. </p>
  
  <pre><code>$.each( body.message, function( key, value ) { 
    alert(value);
  } 
  </code></pre>
  
  <p>Is there an smart way of doing this?</p>
