To see what would happen, reporters for NPR's Planet Money pooled their money and bought a toxic asset for $1,000. At 99% off, it seemed like a bargain. This week, "Toxie," as they dubbed their pet, gave up the ghost. Contrary to expectation, she was killed not by foreclosures, but by loan modifications, which reduced the amount of cash flowing into the bond. Planet Money tells the whole story in this awesome and hilarious animation.
