Well, that doesn't look so great!  Does Anyone know how to fix this?

Here is the code:

<pre><div id="fb-root">
</div>
<script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script>

<div class="fb-post" data-href="https://www.facebook.com/permalink.php?story_fbid=639853629380655&amp;id=112654462100577">
<div class="fb-xfbml-parse-ignore">
