[jQuery] irc | selecting

im having hard time connecting to IRC. is it down or am i stupid?
anyways I have a rather basic question about jquery:
<div>
<input>
<a name="something" >a</a>
</div>
<javascript>
$('.something').click(function(){
//how can I select the input element to manipulate
//( i managed to select the wrapper element like so:
var wrapper = $(this).parent('div');
)
});
</javascript>
thank you!
