You put ANYTHING in a DnD and you better be prepared for your players to fight it or fuck it and usually both

Not sure if you're really asking or if its rhetorical, so forgive me if I'm way off, but in doubt it is a reference to how rpg players (of the tabletop kind) will (try to) do inane shit at some point in any given game, such as fucking a dragon. Hence the great overlap between the respective skillsets of managers and dungeon masters. And I assume parents of toddlers.
