jQuery parent().("selector")

I have this HTML code:

<tr>
  <td><input type="checkbox" class="chk" /></td>
  <td><div class="disabled">text to hide 1</div></td>
  <td><div class="disabled">text to hide 2</div></td>
</tr>

I'm using jQuery to hide all class="disabled" items:

$("div.disabled").hide() ;

I want to show disabled divs when I click the checkbox in the same row (tr). I tried

$("input.chk").click(function(){
  $(this).parent().parent().(".disabled").show();
}) ;

but it doesn't work.
