A 77-year-old Florida woman went to the bank to withdraw some cash and was shocked to find out she had $1 billion in her checking account. Julia Yonkowski was trying to get $20 from the ATM at a Chase in Largo when she found the gigantic mistake. A whopping $999,985,855.94 appeared in her account balance, to be exact. She knew it was a mistake right away, and contacted the bank to let them know what was going on. The next time she looked, the checking account was down to its correct amount.
