Include tags in the body of a post

it feel like this should be easy. I want to add the post tags inside the body of some posts. I was thinking that creating a shortcode may be the answer. I came across these 2 pieces of code:

To display the tags…

<p><?php the_tags(); ?></p>

To create a shortcode…

function show_current_year(){
    return date('Y');
}
add_shortcode('show_current_year', 'show_current_year');

I can’t combine the 2! Can anyone help? The only other solution would be to insert the php directly in the post but I think I’d need a plug-in to do that and I’m a bit wary.
