Bug Corpses
I recently replaced a light bulb in my living room floor lamp and was surprised how filthy the shade had gotten. Seeing the inner surface go from a light brown to clean white plastic filled me with both satisfaction and shame. The design of the lamp has a crinkly posable neck, but luckily I've just left it vertical. Because if I had tilted it, I would have been showered with cascading dust and bug corpses.
