I’ve always been amused by the reasons that the MPAA give for their ratings, which are displayed just below the letter rating in the blue or green card that precedes a preview. Gunaxin has taken the liberty of compiling an awesome list of the twenty best MPAA ratings, and man, some of them are just priceless. My favourite? 3 Ninjas Knuckle Up, rated PG-13 for “non-stop ninja action”. I must admit, the promise of non-stop ninja action actually makes me want to see this movie way more than I did before I saw this list.
