Dollarydoo
Dollarydoos are the fictional currency used in Australia in the 1995 The Simpsons episode " Bart Vs. Australia".
A petition was started on Change.org in October 2015 by an Australian named Thomas Probst to change the national currency of Australia from the Australian Dollar to the Dollarydoo, receiving tens of thousands of signatures and garnering worldwide media attention.
For the Australian currency, see, Australian Dollar.
