'Bah!' said Scrooge, 'Humbug!'
'Christmas a humbug, uncle!' said Scrooge's nephew. 'You don't mean that, I am sure?'
-- from A Christmas Carol
A nitpicky bit of holiday trivia: Ebenezer Scrooge never actually says "Bah humbug!" as a phrase. They were always two different words, Bah! being the interjection and humbug meaning, according to the trusty Webster 1913, "something contrived in order to deceive and mislead" -- referring, of course, to Christmas itself (and occasionally Marley's Ghost).
