Have you heard of the Treasury Department's Conscience Fund?
Here's a little bit of trivia for the day that I recently learned about and thought was interesting. The US Department of the Treasury maintains a gift fund called the Conscience Fund that people can donate money/items to. Apparently, its purpose is to help people sleep better at night that have defrauded the government. According to Wikipedia (for what it's worth), they have collected $5.7 million since its creation in 1811. I doubt many people are inclined to donate to the fund nowadays, though.
