[How To] Exclude Current Posts from 2nd loop

I am pulling 5 random posts and i didn’t want it to show the current post in this loop, so here is how to do it:

<?php
global $wp_query;
$thePostID = $wp_query->post->ID;
$rand_posts = get_posts('numberposts=5&exclude='.$thePostID.'&orderby=rand');
 foreach( $rand_posts as $post ) :?>

<h3><?php the_title(); ?></h3>
 <?php endforeach; ?>
