George (as in Washington) is on the $1 bill.
Have you ever thought about the $1 bills you receive and spend? Where they have been and where they go after you spend them?
Neither have I.
But, someone was curious. Hence, the creation of "Where's George."
Curious people mark the $1's they receive with a special "Where's George" stamp and enter the bill serial number on-line.
I'm a curious person.
I bought a stamp.
