There aren't many people who would come across thousands of dollars in an item they just bought, there are even fewer who would return it.
Rabbi Noah Muroff and his wife of New Haven, Connecticut purchased a desk on Craigslist for $150. When they couldn't get it through the front door of their house, they took it apart, only to discover a whopping $98,000 was in the desk.
However, Noah did the right thing, called the previous owner immediately and returned the money.
