This one is from The Rook by Daniel O’Malley. I use it now, frequently, when confronted with something that confuses me.
Its simply this.
“This Duck tells me nothing!”
And no, I will not put it into context. Let it confuse you as the things I use it in reference to confuse me!
If you wanna know where it comes from, well, read The Rook then. And then all will be revealed.
