[wp-forums] What is this script?

[mrmist]

Does anyone else see this, or is it just my browser?

Viewing in Opera, I get this error

JavaScript - http://crazyegg.com/pages/scripts/23144.js?1277971895344
Linked script not loaded

Which relates to this bit of source code

<script type="text/javascript">
//<![CDATA[
  document.write('<scr'+'ipt
src="http://crazyegg.com/pages/scripts/23144.js?'+(new
Date()).getTime()+'" type="text/javascript"></'+'script>');
//]]>
</script>

If other people see it, what the heck is it?  (The script appears in
other browsers, too)
