Oxford Comma by Vampire Weekend
I was so amused by the title because, just recently, I randomly learned what the Oxford Comma is. I will proceed in giving you a grammar lesson:
Which sentence is correct?:
I am festive, extravagant, and a grammar-freak.
or...
I am festive, extravagant and a grammar freak.
The second sentence. As you hopefully noticed, sentence no. 2 lacked a comma for the third listed article. So the Oxford Comma is indicated correctly when you leave out the comma linking 'and' in a list of items.
Just had to get that off my chest. I like feeling smart.
