I have something to tell you that may reduce your belief in my love for grammar.
I didn't know what the Oxford comma was until after I graduated with an English degree (and courses in linguistics). I had to look it up on (oh, this hurts) Wikipedia. I know, I know, I should have gone to a better-credited source, but it's so easy to just pop over there and type in your search. For the record, I did follow the wiki search with a perusal of the OWL at Purdue, just to verify what I was reading.
But anyway, once I knew what it was--ah! the serial comma!--I realized that it was the comma I actually quite love. It's the one that comes after the last item before the conjunction in a list.
This is all a bit of history (I almost wrote "backstory" before remembering this article) to tell you why, exactly, I loved and laughed at this story on NPR.
I am so happy to hear that the Oxford Comma is safe (because I am not a fan of unnecessary ambiguity, unless it serves some rhetorical purpose).
