Kyle's cousin, Kyle Schwartz from Connecticut, comes to live in South Park due to his mother's health. While Kyle is initially excited about seeing his cousin for the first time, he is shocked to see that he is a much overly-stereotyped version of a Jewish person (e.g., constantly complaining about everything, Yiddish accent, highly sensitive to the dryness of the air, breathes heavily, vibrates his soft palate every time he exhales making a sound akin to a snore, allergic to most meats excluding fish, and penny-pinching in nature). Kyle is told by his mother to take care of his cousin, and it is his responsibility to make sure cousin Kyle fits in at school.
Kyle promises to pay Cartman $40 if he doesn't make fun of his cousin. Cartman tries as hard as he can but the temptation is to great for him to resist, he says something about concentration camps in class and blows the deal. When Cartman is making up excuses, cousin Kyle happens to hear. But instead of getting frustrated, he blames Kyle for offering too much.
The Boys all soon realize that Kyle's cousin is just way too annoying to live in South Park with them, especially Kyle who thinks that his cousin has ruined the reputation of Jews in South Park. They constantly tries to get rid of Kyle's cousin, by tying him to the back of a bus to Connecticut while he is on a sled, tricking him onto a plane to Antarctica, etc. However, Kyle's cousin always finds a way to come back to South Park in a manner parodying a Looney Tunes character, and every time with his infamous catchphrase "I'm back".
Meanwhile, Mr. Garrison misses his flight to Cheyenne because of inefficient and frustrating airline check-ins. Having had enough of it Mr. Garrison decides to invent his own vehicle to put airline companies out of business. Inspired by watching singer Enrique Iglesias' sexualized singing on TV and by gyroscopes, 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 than any other vehicle. The only problem is that it is controlled by an uncomfortable method: using four "flexi-grip handles" that somewhat resemble erect penises; two used by the hands, one in the mouth, and a fourth handle which is inserted into the anus. A number of tycoons are invited to IT's initial release, all of them are impressed by IT's sci-fi look and incredible speed.
Despite this unorthodox control mechanism (which is uncomfortable to everyone except Mr. Garrison and elderly women), it is still considered better than the airlines and Mr. Garrison becomes a smashing success across the country with two million ITs sold. Even aviation enthusiast John Travolta decides that "IT" "beats dealing with the airline companies.". Later Randy finds that the same buttons that are found on the handles are found on the sides of the vehicle rendering the grips useless, something which Garrison reluctantly admits.
However, the government decides to bail out the airlines from going under because of "IT". To ensure the airlines' dominance as a mode of transport to make sure none of the people working for them lose their jobs, the government ends up outlawing "IT" and makes using it a criminal act, despite acknowledging that the airlines are failing because of their own incompetence and inefficiency.
As a result, Kyle's cousin, who had invested in "IT", gets a $5,000,000 bailout payment and decides to return home to Connecticut to take care of his sick mother. Because of this new found wealth, the boys suddenly change their plan and try to persuade him to stay in South Park, but words get stuck in their mouths and they are unable to do an "I've learnt something today" talk. To their surprise, Kyle's cousin says that he wants to leave because they are "douchebags" and calls them hick jock rednecks out of a "stereotype catalog". He ultimately leaves, dashing their chances to share in his new wealth. Cartman blames Kyle for his departure, saying "Good job, Jew!" just as the episode ends.
