Quick! What's less funny than Scary Movie? Date Movie! And what's less funny than Date Movie? Epic Movie! And what's less funny than Epic Movie?

Why, it's Meet The Spartans - the film that does for 300 what Epic Movie did for Superman. And Meet The Spartans is the new number one movie at the weekend box office, even though it looks about as funny as that operation where you pull parasitic guinea worms out of your leg.

Still, Meet The Spartans wasn't the only ridiculous parody to chart high in the US weekend box office - Rambo came in at number two.
