Three young housemates bought an old couch at a Salvation Army store for $20. When they brought it home they found wads of $100 bills stuffed inside. The total was over $40,000. They dreamed of ways to spend the money, but then they saw a name on one of the envelopes, which led them to a prior owner, a widow who lived in a rough neighborhood. It turned out that her late husband had put money in the couch for his wife to use when he was no longer around (NPR, May 16).
