apology, but an unsatisfied Parliament demands Bart receive a "booting" — a kick on the buttocks with an oversize boot — as corporal punishment. Desperate, Bart and Homer escape and the family flees to the embassy, chased by a large, angry mob. After a stand-off, the two governments propose a compromise: one kick from the Prime Minister, through the gate of the embassy, with a regular wing-tip shoe. Marge protests, but Bart agrees to the punishment. However, Bart dodges the kick, moons the Australians with the words "Don't tread on me" written on his buttocks, and hums "The Star-Spangled Banner". The outraged mob storms the embassy, and the Simpsons and the embassy staff are evacuated by helicopter. From the air, the Simpsons notice that Bart's bullfrog has reproduced, and its offspring are wreaking havoc on Australia's ecosystem and farms. They gleefully laugh, unaware a koala has stowed away aboard their helicopter and may inadvertently be introduced to U.S. territories. Production The episode was written by Bill Oakley and Josh Weinstein, and directed by Wes Archer. The writing staff wanted to do an episode where the Simpson family traveled to Australia, because they thought everyone in Australia had a good sense of humor and that they "would get the jokes". The staff had previously poked fun at several American institutions on the show, and they thought it would be interesting to poke fun at a whole nation. They designed Australia and the Australian people very inaccurately and many things were completely made up for fun. The animators, however, got two Australian tourist guides to help them out with the design of the Australian landscape and buildings, as well as the US Embassy. The writers did research on the Coriolis effect for this episode. Lisa's explanation of the effect is incorrect; it affects global weather patterns and is caused by the spinning of the globe on its axis. The distances involved when a toilet or sink drains are much too small to be affected by it. In 1999, Fox Studios Australia in Sydney used a different version of "Bart vs. Australia" as part of their The Simpsons attraction, called The Simpsons Down Under. They had contacted the Simpsons writing staff and asked if they would write the screenplay for a ride in their attraction, based on this episode. The episode was re-edited and re-animated for the ride and new scenes were included.
