So who's annoying me today?
Answer: Thomas Henry Huxley, because he wrote in a letter to George John Romanes (April 28, 1893): "The double negative is Shakspearian. See Hamlet, act ii. sc. 2."
What the hell kind of citation is that? Hamlet act 2 scene 2 is 1,800 lines long!
Huxley, if you hadn't died 107 years ago, I'd send you a mean note.
