The attraction featured motion capture technology, allowing audience members' faces and expressions to be transformed into moving cartoon characters. Cultural references The plot of the episode is based on the story of Michael Fay, an American teenager who was caned in Singapore in 1994 for vandalizing cars. This episode perpetuated a popular myth that the Coriolis effect affects the motion of drains in the Northern and Southern Hemispheres. In reality, the Coriolis effect affects global weather patterns. The amount of water in a toilet or sink is much too small to be affected by it. During the scene in which Bart calls various locations in the Southern Hemisphere, he calls a car phone belonging to a man who appears to be an elderly version of Adolf Hitler alive in Buenos Aires, referencing the conspiracy theory that Hitler faked his death and fled to Argentina at the end of World War II. When Bart is talking to the boy's father on the phone, he says, "Hey! I think I hear a dingo eating your baby!", referencing the case of Azaria Chamberlain, a 10-week-old baby who was killed by dingoes. The bullfrogs taking over Australia and destroying all the crops is a reference to the cane toad, originally introduced to Australia in order to protect sugar canes from the cane beetle, but which became a pest in the country. When the Simpson family go to an Australian pub, Bart plays with a pocketknife at the table and a man asks him, "You call that a knife?", and as the man draws a spoon from his pocket he says, "This is a knife." The scene is a reference to a famous scene from Crocodile Dundee, in which Mick Dundee is threatened by some thugs with a switchblade, and Mick takes out a bowie knife and says; "That's not a knife; that's a knife!" The Simpson family is shown a slide show by the US Department of State depicting a boarded up cinema with a marquee reading "Yahoo Serious Festival", in reference to the Australian actor and director Yahoo Serious. Wez, one of the characters from the 1981 film Mad Max 2: The Road Warrior, is seen in the Australian mob that chases Bart and Homer to the US Embassy. The scene where the Simpsons family and the embassy staff get evacuated via helicopter is a reference to the helicopter evacuation of the U.S.
