Goody two-shoes couple finds extra $50 billion in their bank account, promptly return it
We would have totally done the exact same thing... totally.

There are approximately two (2) people in the entire world who conceivably deserve $50 billion: Beyoncé, and Dolly Parton. But other than them, we can’t think of any instance in which that amount of genuinely inconceivable wealth shouldn’t be interpreted as a crime against humanity.
That said, we wouldn’t hold it against the Average Joe if, upon stumbling upon an extra $50 billion in their checking account one morning, they suddenly absconded to a Caribbean nation with nebulous tax laws. That’s recently what happened to a couple in Baton Rouge, Louisiana… well, the first part about an extra $50B in the bank, not the absconding part. They actually did the “right” (read: boring) thing and returned all of it.
As Newsweek reports, the James family was somewhat surprised to find the approximate wealth of Michael Bloomberg suddenly in their bank account one morning after attempting to transfer money to their daughter. “It was crazy just to see what it looks like because I’ve never seen that many zeros in my life,” Darren James told BR Proud. “I wasn’t going to keep it. The thing that was most baffling was, we don’t even know where it came from. We don’t know anybody with that kind of money.”
