One fine spring morning, we woke up to find that our beloved Big Blue Bear — Lawrence Argent's "I See What You Mean,"a sculpture of a giant bear peering into the Colorado Convention Center — had taken a big blue dump. It was not the first time our own Ursa Major had been the focus of guerrilla street art (in 2011, the Ladies Fancywork Society attached him to a gigantic blue-yarn ball and chain), but this urban twist on the old adage about a bear shitting in the woods was — how should we say it? — an instance of scatalogical genius, though it left the city in a tizzy about what to do with the perfectly matched papier-mâché turd. As far as we know, the great talent behind the blue poo never came forward, and therefore, the bear pie must have been flushed, as promised, by the city. But the prank left behind at least one enduring message: Denver has a sense of humor.
