Pulling the tags from a post

Hi all,

After a bit of digging around, I have found this little nugget of code…:

<?php
$post_id = 244;
$my_post = get_post($post_id);
$title = $my_post->post_title;
echo 'Tags: ';
echo $title;
?>

…Which works fine for pulling a specific post title, but how do i edit this to get a specific post tags instead?

Something along these lins im assuming?:

<?php
$post_id = 244;
$my_post = get_post($post_id);
$tags = $my_post->post_tags;
echo 'Tags: ';
echo $tags;
?>

But it doesn’t work!

Any ideas?
