$("div") how toget div.children.text();?

Hello,
Can someone explain to me how to get the value(text) from div id="two".



<div id="content" class="content">
<div id="one" class="test">joop</div>
<div id="two" class="test">kees</div>
<div id="tree" class="test">gert</div>
</div>

I try ,
$(this).click(function() {
alert($(this).html());
});
but this is wrong.

Thanks, Jan
