Geeker, apropos of nothing, thinking of WOOD-HOUSE, we used to joke with our younger siblings learning calculus: if the integral of dx/x = log x, what is the Integral of dcabin/cabin? They, usually, swiftly responded with LOG CABIN. We would then, with an air of superiority, say “no - it’s HOUSEBOAT, as it’s an indefinite integral so it’s LOG CABIN + C” . Must get out more.
