In some contexts, I might say (indeed, I have said...): "A facility for quotation covers the absence of original thought."
But I would never in real life say: "As Lord Peter Wimsey said, 'a facility for quotation covers the absence of original thought.'"
And I would certainly never say, "As Lord Peter Wimsey said in Dorothy Sayers's 'Gaudy Night (tm)':..."
I have used the second, or its equivalent, in real conversation. I may even have used the last (without the "(tm)"
) - but then not everyone I speak with are fans of the same books or shows that I am, so sometimes an explanation is not unreasonable - it's not always condescending. I grant you that it's not usual, but "would never say" is a little extreme.
PS. I love the example, by the way. It's so wonderfully ... there must be a word for it, if there's not there should be.
