Heh, like the rest of our crap is publishable?
As a writer, your first audience should be you. If other people enjoy it, good, but your writing should teach you something about yourself...
Yeah, yeah, I know...and realistically, I know it isn't...but the other stories I can at least DREAM of having published. So...even though this is easy and fairly fun, it rankles a bit.
But it's still a way of honing my skills, and therefore worth doing.
Besides, as one of my ex-taglines said..."Anything worth doing is worth doing badly." ;-)
