[jQuery] wrap isn't working, or I'm doing it wrong?

[Geuis]

There's a page of some damn tables that I'm trying to redo
dynamically. Its a page I don't have control over so this code is
running from a bookmarklet in my browser. I'm trying to sample out the
content I want and re-wrap it in an an unordered list. I can't get
the .wrap function to work.

The sample html looks like this:
<table>
        <tr>
                <td class="title">
                        <a href="link">Link</a>
                </td>
        </tr>
</table>

I'm using this jQuery code to 1) sample the data I want. 2) destroy
the contents of the page, write the start/end ul tags. 3) loop through
the sampled data, wrap <li> tags around them, then append to the <ul>.
However, it will write out the contents but doesn't wrap the <li>
tags.

anchors = $("td.title[valign!='top']").children();

$('body').html("<ul id='hn'></ul>");

anchors.each(function(){
        $("#hn").append( $(this).wrap("<li></li>"));
});
