When I was a kid I had a kids savings account at the local bank. When you turned 12 they made you switch to a regular account joint with a parent. My mom took me to the bank to switch the account after I turned 12. Somehow during the account conversion the teller accidentally deposited a 7 figure number starting with a 7 into the kids account. Not sure if she was trying to type in the account number for the new account or a confirmation number but she printed out the updated passbook to show the final balance before she caught the error. She did catch the error and the new joint account did not have 7 plus million dollars in it but I do still have that passbook from the kids account to commemorate the one minute when at 12 years old that I had over 7M.

Better to be a satoshi millionaire anyways.
