.each() find the last item and create an if statement
<p>I've got the following jQuery,</p>

<pre><code>function animTweets($tweets) {
    $tweets.each(function () {
        var $tweet = $(this);
        $('#twitterTile').queue('myQueue', function (next) {
            $tweet.animate({top: 0, height: 'show'},
                        {duration: 300,
                         queue: false,
                         complete: next
                        });
        }).delay(1E10, 'myQueue');
    });
}
</code></pre>

<p>It iterates through items contained in a list ($tweets).</p>

<p>How can I create an <code>if</code> statement so that the last item has a different animation?</p>
