“More from this Category”, excluding current post

In the sidebar of the the Mimbo theme, there is a module called “More from this Category”. The relevant code is:

<?php if ( is_single() ) :
global $post;
$categories = get_the_category();
foreach ($categories as $category) :
?>
<li><h2>More from this category</h2>
<ul class="bullets">
<?php
$posts = get_posts('numberposts=10&category='. $category->term_id);
foreach($posts as $post) :
?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>

Anyway, I’m building a similar module for my new theme, but unlike Mimbo, I want to exclude the current post from the list so there’s no redundancy. Any simple way to do that?
