Grammar lovers today were saddened, shocked, and mightily displeased at the news that the P.R. department of the University of Oxford has decided to drop the comma for which it is so justly famed.

Cue the collective gasps of horror. The last time the nerd community was this cruelly betrayed, George Lucas was sitting at his desk, thinking, "I shall call him Jar Jar."
