Today in Old Town I was walking into a stationary store when I noticed the sign on the door. It said "Were open!" Uh...
*Edited to add: I know this sign was not in need of an Oxford Comma but I like the song by Vampire Weekend aaaand I like Oxford Commas. My favorite demonstration of the need for an Oxford Comma is this sentence on a book's dedication page: "I'd like to thank my parents, Ayn Rand and God." Some parents to have, huh?
