The Entity

The Entity is episode #510 of South Park.

Plot
In the episode, Kyle's cousin, Kyle Schwartz from Connecticut, comes to live in South Park due to his mothers ailing health back in Connecticut. While Kyle was 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 (e.g., constantly complaining about everything, highly sensitive to the dryness of the air, allergic to most meats excluding fish, and penny-pinching in nature). Kyle is told by his mother to take care of his cousin, but 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's cousin, by tying him to the back of a bus 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.

Meanwhile, Mr. Garrison, tired of the inefficient and frustrating airline check-ins, decides to invent his own vehicle. Inspired by watching singer Enrique Iglesias's sexualized singing on TV and by gyroscopes, he invents the gyroscope-powered monowheel "IT" (supposedly a parody of the Segway, which was code-named "IT", although this episode aired before the unveiling of the Segway Scooter). "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" that somewhat resemble erect penises; two used by the hands, one in the mouth, and a fourth handle which is inserted into the anus. 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 is a smashing success. Even aviation enthusiast John Travolta decides that "IT" "beats dealing with the airline companies."

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, the government ends up outlawing "IT" and makes using it a criminal act. As a result, Kyle's cousin, who had invested in "IT", gets a $5,000,000 bail out 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 get him to stay in South Park. To their surprise, Kyle's cousin says that he wants to leave because they are "douchebags" and calls them 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 before the episode ends.

Goofs
Kyle Schwartz is seen being collected outside his flight gate by the Broflovskis. However, because this episode takes place after 9/11, the Broflovskis, due to the fact that they're not passengers, would not even be allowed past the airport checkpoint. This goof is repeated in The Losing Edge.
