[jQuery] hiding checkbox AND label?

[Priest, James (NIH/NIEHS) [C]]

Argh - I'm close - but so far I can't seem to hide BOTH the checkbox and
label:

$('h3').click(function() {
$(this).next('.details').find("input:checkbox").not(":checked").hide();
});

OR 

$('h3').click(function() {
$('input:checkbox').each(function() {
        if (!this.checked)
        {
              $(this).next().hide();
        }
        });
 });

Both hide the checkbox only. The label remains!!  

I've tried a few things with parent().next() but either I can remove the
checkbox OR the label but never both??

I'm sure I'm missing something simple here????

Thanks,
Jim
