Further question: Is the movie really a parody? If so, exactly what is it parodying? The "Stormtroopers" bit at the end may have the nature of a parody, but the rest strikes not so much as a parody as just an attempt at humor. If you sit and analyse anything long enough, you can ascribe nearly any attribute to it, even being a "parody" of something. I'm just plain not certain that the spot parodies anything deliberately; it would probably take a court to sort it out (though I'd personally be satisfied to talk to the authors for a bit).
