(The complete plot for this South Park Episode)
Kyle's cousin, Kyle Schwartz from Connecticut, comes to live in South Park due to his mother's ailing health back at home. While Kyle is initially excited about seeing his cousin for the first time, he is shocked to see that he is an overly-stereotyped version of a Jew, wearing his hair in a style similar to Woody Allen, and has annoying characteristics, as he is constantly complaining about everything, highly sensitive to the dryness of the air, allergic to most meats excluding fish, and penny-pinching in nature. To make matters worse for Kyle, he is nicknamed "Kyle 2" by his mother and his cousin is still called "Kyle." Kyle is told by his mother to take care of his cousin. Kyle, fearing that Cartman, a staunch anti-Semite, will "tear this kid apart," attempts to bribe Cartman with $40 to not make fun of him. Cartman, wanting the bribe, struggles to avoid mocking Kyle's cousin, only to blow it spectacularly when he makes a concentration camp joke in class. The children all soon realize that Kyle's cousin is just too annoying to live in South Park with them. Much of this episode then goes on to have the boys constantly trying to get rid of Kyle Schwartz, by tying him to the back of a bus while he is on a sled, tricking him onto a plane to Antarctica. However, Kyle Schwartz always finds a way to come back to South Park.Meanwhile, Mr. Garrison, tired of the inefficient and frustrating airline check-ins, decides to invent his own vehicle. Inspired by watching singer Enrique Iglesias singing on TV, he invents the gyroscope-powered monowheel "It." "It" can go up to two hundred miles per hour, gets three hundred miles to the gallon, and is an all-around better mode of travel. The only problem is that "It" is controlled by an uncomfortable method; using four "flexi-grip handles". It also transpires that the vehicle can be operated with buttons too, making the handles controls an unnecessary discomfort. Garrison invites many important investors such as Bill Gates, Steve Jobs and Yasmine Bleeth to see how "It" works. Despite this weird control mechanism, "It" is still considered better than the airlines and Garrison is a smashing success. Even aviation enthusiast John Travolta decides that "IT" beats dealing with the airline companies. The airport is now fully deserted and yet the airline industry's inefficiency is, if anything, amplified by the lack of people in the airport.
The government decides to bail out the airlines from going under because of "It". To ensure the airlines' dominance as a mode of transport and the job security of everyone working for it, the government ends up outlawing "It" and makes using it a criminal act, even though, according to Garrison and confirmed by one of the arresting agents, it is the airline industry's own fault that it is doing so badly. As a result, Kyle's cousin, who had invested in "It", gets a $5 million bail-out payment and decides to return home to Connecticut to take care of his sick mother. The boys suddenly change their plan and try to get him to stay in South Park, but he rejects them for being such "douchebags" and "stereotypical"
