Didn't know if I should re-tell this story or not but here it goes.

About 6 or 7 years while at the airport my mom withdrew some cash from an ATM. Nothing strange but she noticed the checking balance was a few thousand too high. No big deal, probably just a printing error or something with the ATM.

Fast forward a week. Getting back from a trip my dad goes to make a withdrawal from a local ATM. Receipt comes out this time about 20 or 30 million over. He thinks it was just an ATM error too and doesn't worry about it.

Few days later, same story but this time it's a couple hundred million. My dad calls the bank and the rep on the phone thinks it's a joke. Next day, another hundred million. This time he drives to our local bank, stands in line patiently, calmly walks up to the teller and explains what happened. He then proceeds to tell the teller with a straight face that he is "very disappointed with the security of his account" and that he "feels it's only fair that he should get to keep any interest that has accumulated since the error started." The teller stands there speechless before my Dad busts up laughing.

They fixed the error without question the same day and we didn't really talk about it ever again. I guess my Dad is just that awesome that he never even joked with us about keeping a penny of it. I still like my idea of taking out a million or so in cash and then walk in with the cash when he went to tell alert them.
