Euros are Europe's version of dollars. If the dollar was a foodstamp. Bigger money values are printed on bigger pieces of paper to make them easier to steal. They are all in different colors, sizes, and shapes so it wont offend the other European neighbors. If you find yourself in Europe and you notice that the pieces of trash that you see on the street are actually Euros, they are not even worth the paper that are printed on (not even to use as toilet paper). Its like monopoly money, except less fun to play with, and they yell at you more when you pay with it than when the bank catches you stealing a 500; actually, that is a lie banks wold actually give away Euros to their customers and thieves but no one wants it.
