It sounds like Austin Powers picked the number. Someone in Louisiana is suing the federal government for more than three quadrillion dollars over damage from Hurricane Katrina. To put that in perspective, there are 5 commas in the number ($3,014,170,389,176,410). You'll need more than two forms of ID to cash that check.
For some perspective, if you piled a quadrillion pennies on top of each other, they would reach Saturn. On the other hand, if you gave Mike Gravel a quadrillion dollars, he still couldn't be elected President.
