These are pictures of the Chaitén volcano erupting in Chile (the country, not the delicious mixture of beans, meat and spices) and creating a "dirty thunderstorm". Dirty thunderstorms are caused by the incredible amount of static electricity generated in a volcano's ash plume and are not to be confused with "dirty thunderwearstorms" which are created when a coworker (i.e. The Superficial Writer -- thanks a lot dude) is taking his afternoon nap on the only commode in the building and there's nowhere else to relieve yourself.
