I never much wondered about Oxford commas before the song Oxford Comma from Vampire Weekend caught my attention. The very first line is "Who gives a fuck about an Oxford comma?" and I have realized that I do. I give a fuck. I actually feel very strongly about it. I just looks better, in my opinion.
For those of you wondering what an Oxford comma is it's the comma that comes before the "and" in a series.
For instance: When I went to the store I bought a peach, bacon, and eggs.
The comma after the bacon is the comma in question. It's not necessarily needed but I think it's a nice addition to a sentence.
I am sounding more and more like a grammatical nutcase. I swear I'm not really.
