Claim: After successfully robbing a bank, very polite Japanese thieves penned a thank-you note to that financial institution.
Origins: And I thought I was compulsive about thank-you notes:
Ten days after the biggest bank heist — $5.4 million — in Japan's history, the Kobe branch of Fukutoku Bank received a letter of gratitude, presumably from the robbers. "Thank you very much for the bonus," the letter read. "We can live on this loot for life."
