LOL, I loved that, so funny!
The national currency of Poland is the litre (litr). It is produced in denominations of 100mL, 200mL, 355mL, 500mL, 1L and 0,7L. Unlike most other countries, polish money is not minted from metal or printed on paper, but rather is distributed in the form of the transparent liquid, described below. An exchange rate of roughly 8 euros for 1 litre is typically available. Litres are produced by many privately licensed foundries which are owned and strictly controlled by the aristocracy. Counterfeiting is rampant (particularly outside the major cities and in student dormitories) in Poland since litres can be distilled from rain or illegally drawn from rivers.
