Years ago, for whatever reason, there was a job position for a resident nerd on ships that traveled around the world. I don't know why it existed - and I don't know if it still does - but I do know that one particular British nerd became famous as a result of it. He was a young man who was aiming to be a doctor until - like me - he discovered there wasn't much good he could do for people while he was puking or passed out on the floor. What to do? Become a clergyman, I suppose... Nah. Jump on a boat and be the resident nerd!
So one day, while strolling on a beach in Chile (the life of a resident nerd is tough), he picked up a rock. Upon nerdy close examination, he found a mysterious creature inside it. It looked a lot like a barnacle, except it was missing the main feature of a barnacle: the barnacle-y shell. Everyone knows barnacles secrete a shell. That's what makes them barnacles! Apparently what everyone knows isn't exactly true. Mr. Resident Nerd had found himself a barnacle that avoids the whole secretion thing and simply burrows into a rock.
Now, I know what you're thinking. If you're not a nerd you're thinking, "I'm surprised I've gotten this far in the story. Where did I see those chairs I really liked...?" If you're a nerd, however, you're wondering if Mr. Resident Nerd is haunted by the discrepancy for 35 years and devotes every waking hour for 8 of those years to nothing but studying every living and fossilized barnacle known to humankind in the hopes of figuring out what really defines a barnacle. Let me help both of you out. Non-nerds, you saw them at INspiration Interiors, but they were kinda pricey. Nerds: yes.
