The four boys wait at the bus-stop wearing gas-masks for defence from anthrax . Since the September 11 attacks , everything has changed in South Park : everyone is afraid of terrorists , American flags are plastered everywhere to show widespread patriotism and Stan 's mother has become catatonic and lies on the couch all day watching the news . Upon arriving at school , the boys discover that they must , in response to President Bush 's request for charity to Afghanistan , donate a dollar . The boys ' dollars are sent to four Afghan kids who closely resemble them . Though their town is in ruins after excessive American bombing and the unconverted American money is unusable in Afghanistan , in return the four Afghan boys send the South Park boys a goat in the mail . The boys realize that their parents will not let them keep the goat and so try to send it back to Afghanistan . Since only U.S. military planes are flying over the country , they can only do it by sneaking the goat aboard a military plane . They sneak into a nearby base , able to do so when the guards mistake the goat for Stevie Nicks there for a USO show ; however , the boys wind up on the plane too , and are sent to Afghanistan
