[jQuery] Single queued function after animation

[suprfish]

How can I call a single function after an animation? That is, a
function that does not iterate upon each matched element but only
once?

<ul>
<li>1</li>
<li>2</li>
<li>3</li>
</ul>

$('ul li').animate({left: 450}, "slow").queue(function(){ /* this
function should only iterate once */});

If I simply call the function after the animation in the code, it
seems to be called right after the animation starts.

Thanks,
