More Google weirdness. That hit doesn’t show up when I search. I can see it when I click the link, but it’s invisible to me otherwise. (It’s not a US/Canadian thing, because I can’t see it when I log in through a US-based VPN. Besides, sometimes Canadian Google doesn’t give you the full of the text because of different copyright laws, but I don’t think they restrict the appearance of hits entirely.)
A better instance of the phrase may need to be less specific than this; i.e., not address a specific question.
I agree that this isn’t a use of the generic phrase, rather it’s a response to a stated question. But if there is a pattern of use of these words into the twentieth century, this is likely the tradition the catchphrase arises from.
