Exclude current user in SQL

Hi,

I have a plugin in the works that I’m trying to modify, and I’m having no luck with getting the current user ID excluded from a sql statement that displays a list of users that have liked a post.

/**
 * Return user names that liked a post
 * !!try to exclude the current user!!
 * @global $wpdb
 * @param int $pid Post ID
 * @return array Users that liked the post
 */
function like_get_named( $pid ) {
	global $wpdb;

	$results = $wpdb->get_results ( $wpdb->prepare( "SELECT like_uid FROM " . $wpdb->prefix . "likes WHERE like_pid=%d", $pid), ARRAY_N );

        if($results === null)
	return apply_filters('like_get_named', array());
        $results = array_map('_like_flatten_array', $results);
        return apply_filters('like_get_named', $results);
}

So I’m looking for a facebookesque display like

You, author1 and author2 liked this post

But instead I’m getting

You, my-name and author1 and author2 liked this post
