A work-related exchange:
Charlie: Do you have to print a photo of a leopard in spot color?
Gary: Depends on the dot gain of the image.
This is very geeky printing humor, but it made us happy. (Though we usually work on typesetting black and white text, lately we’ve been working with color files for book covers, which is why we suddenly care about spot color, as opposed to process/CMYK color.)
