How do I turn off the left/right box titles?

These titles are inserted in...

includes/templates/NAME_OF_TEMPLATE/common/tpl_box_default_right.php

Just remove this bit too turn off all titles...
<h3 class="rightBoxHeading" id="<?php echo str_replace('_', '-', $box_id) . 'Heading'; ?>"><?php echo $title; ?></h3>
