Where's George?

There's this cool website called Where's George that you can go to and put in the serial numbers that are on money and it tells you the history of that bill. Where it's been and where your money has gone. I've entered quite a few bills and it's just cool. It tells me how many hits I've gotten on my bills, where they were first received and stuff like that. I think that everyone should do it. It's interesting how far your money travels and how quickly.
