This is also a true story, but I have only my wife and three children to verify it. And I might be able to find an online statement too. Several years ago, I checked my checking account online during one evening and found that my account had $20 million dollars extra in the account, reflecting a deposit made into the account. I called my entire family to the monitor and they all saw the $20,000,000 deposit. I thought we had hit the lottery, and was trying to figure out exactly what I was going to do. I just planning to sit on it for a while and we decided we had to eventually tell the bank about the mistake. The next morning my account reverted back to the correct balance.
