Quote This is yet another quote plugin. It has been a script I’ve used on my personal blog for a few years that I figured I’d share with the rest of the WordPress community.
Basically, it lets you show quotations on your blog in one of three ways:
<ul>
<li><code>quote_this()</code> template tag for your theme template files.</li>
<li><code>[quote-this]</code> shortcode for adding it to your posts and pages.</li>
<li>Quote This widget for use in widget areas.</li>
</ul>

Quote This

Allows the user to call random quotes with the quote_this() function, [quote-this] shortcode, or Quote This widget.
