This episode of This American Life offers three different stories about the unforeseen consequences of trying something new and different. In one, scientists inadvertently discover a way to erase memories from the brain, only to find that people are actually interested in paying for this service. In another, researchers working with pigs inadvertently create disasters with every new improvement they make, and in the last story, two hot dog vendors take on a new business strategy that ends up having a huge effect on people's pent-up emotions.
