11,721,000,000,000,000 (eleven quadrillion, seven hundred twenty one thousand)

A woman in France opened her telephone bill - It was 11,721,000,000,000,000 euros, equal to about 15 quadrillion US dollars.  When she called the telephone company, they said that there was nothing they could do about it, if she did not pay it they would take the money from her bank account, and they offered to set up a payment plan.  Finally, someone was able to adjust the bill to the 117.21 euros she actually owed.
