Yeah, also note that having that script in the header like that, with
the very wide scope of it's target, could lead to some very
unpredictable consequences.

<script type="text/javascript">jQuery("ul").parent("li").addClass("parent");</script>

This script is run at the time that it enters the DOM, which is more
or less immediately after parsing it. But JS typically runs in a
separate thread. So while you're intending it to probably only affect
the nav-menu at this point, it is within the realm of possibility that
some of the rest of the page may load before it actually runs and
does-its-thing. Thus, it is entirely possible for, say, the sidebar
widgets (if they're in a UL/LI structure, which they usually are) to
thus be affected by this JS code as well.

Now, I ain't a theme-reviewer, but I'd certainly fail this code under
any reasonable sanity standard. :) It's just too broad in scope and
it's relying on a side-effect of browser behavior to affect only its
intended targets.
