Remove comment count next to avatars?

Does anyone know how to disable or remove the comment count next to the avatar icons on comments? I have two other blogs and these numbers do not appear.

– You cannot highlight these numbers in the browser
– These numbers do not show when using View Source.

This is the code for that area.

<?php if ($comments) : ?>
	<h3 id="comments"><?php comments_number('No Responses', 'One Response', '% Responses' );?> to “<?php the_title(); ?>”</h3>

<ol class="commentlist">
<?php foreach ($comments as $comment) : ?>

	<li class="<?php echo $oddcomment; ?>" id="comment-<?php comment_ID() ?>">

<div class="commentmetadata">
<div class="grav_icon"><?php echo get_avatar( $comment, 50 ); ?> </div> <b><?php comment_author_link() ?></b>, <?php _e('on'); ?> <a href="#comment-<?php comment_ID() ?>" title=""><?php comment_date('F jS, Y') ?> <?php _e('at');?> <?php comment_time() ?></a>
 		<?php if ($comment->comment_approved == '0') : ?>
		<em><?php _e('Your comment is awaiting moderation.'); ?></em>
 		<?php endif; ?>
</div>

<?php comment_text() ?>
<?php edit_comment_link('Edit Comment','',''); ?>
	</li>

I’ve tried to steal Twenty Ten, Eleven and Twelve’s code but the comments don’t appear if I use that code (even though it shows “3 Responses”). :/
