Grab posts belonging to three categories

Hi,
I want to get posts that match three categories.
For example: if I have three categories, named 1, 2, 3, I want to grab the posts that belong to 1 AND 2 AND 3, and only that posts.
I found a way to make it with two categores:

$args = array(

		'category__and' => array(5739,50),
		'posts_per_page' => 10,
		'orderby' => 'date'
);

But not three.

Thanks in advance.
