[jQuery] jQuery Tabs - Can I Do This?

[jQuery] jQuery Tabs - Can I Do This?

I'm using the Tabs plugin, and have a question.
<ul>
    <li><a href="#tab-1"><span>My First Tab</span></a></li>
    <li><a href="#tab-2"><span>My Second Tab</span></a></li>
    <li><a href="<a href="http://www.someothersite.com/">http://www.someothersite.com/</a>"><span>My Third Tab</span></a></li>
</ul>
<div id="tab-1">
    // my content
</div>
<div id="tab-2">
   // my other content
</div>
Is it possible to get that third tab to actually go to the off-site URL when clicked?  I tried this, but the link was ignored, so I'm not sure if I've done something wrong, or if it's just not possible as written.
Thanks in advance.
