Here is a code sample to do just that.
But keep in mind, this filters the title in maybe all places the title shows up, including the admin.
add_filter('the_title', 'hide_click_title',10,2);
function hide_click_title($t, $id)
{
$post = &get_post($id);
if($post->post_type!='page' || $post->post_name!='my_specific_post_slug') return $t;
return 'filtered title';
}
