I wonder who the first person was that decided urchins qualified as food. I bet it was a really shitty fisherman. His wife was getting pissed that he hadn’t caught anything in like a week, so he goes down to the coast, rounds up a bunch of urchins, and brings them home, telling her they’re a delicacy. Of course she’s stupid as hell (clearly, since she married a fisherman without even finding out if he knows how to fish) and so believes him. Before you know it, every fisherman in town in down by the sea at low tide gathering these goo-filled living pincushions to sell to the masses.
