Oxford Comma Dropped by University of Oxford

You can pry my Oxford comma from my cold, dead, limp hands.

That second comma inserts the pause that the brain needs to properly serialize items in thought; it is the cool, calming, serene oasis between this, that, and the other. I will never give up! I will never surrender!

(I realize this is University of Oxford and not Oxford University press. But still.)
