As I understand it, these things grow on the undersides of boats, and have to be periodically scraped off. This one I actually found in someone's living room, if you can imagine that. Also, I think it would be a linguistic step forward if we started pronouncing "geo" like "gooey", as in a certain horribly repulsive bivalve. Terms like "geodesic dome", "geopolitical ramifications", "National Geographic" and "George W. Bush" would take on fresh new overtones, I believe.
