Why is no one talking about the danger of trash cans that break into your house at night and nibble on your feet? Why don't we talk about hamburgers that expand in your stomach until you burst? Why is nobody talking about the possibility of a large team of dancing robots effectively shutting down all of the subways in Manhattan? Why is nobody talking about the danger of a mutant weed that grows so quickly it engulfs your house in seconds? Why is no one talking about the danger of the sun simply not rising tomorrow?
