I have spent
days hours minutes using my weak google-fu trying to determine the answer to this question, and now, in the spirit of the contemporary entrepreneurial university, I am going to outsource it.
My guesses regarding its origin:
(1) Something from a Smiths song.
(2) A phrase from a Victorian novel.
(3) One of Shakespeare’s minor plays.
(4) Harry Potter?
If this wasn’t actually an allusion, and Hillary came up with the phrase herself, color me impressed.
