Stan Marsh's grandfather Marvin gives him a bejeweled bolo tie, saying that the Jewels & Gems (J&G) Shopping Network, from which he bought it, claimed that its 14 carat gold and diamonds makes it worth $6,000.
Cartman shows his friends the J&G infomercials, where half-senile senior citizens are conned into buying cheap jewelry for their relatives at outrageous prices.
Meanwhile, Cartman decides to get into the infomercial business with Butters as his sidekick, and not only starts offering his classmates cash for gold, he also sets up his own television channel and mimics the tone and techniques of Dean, the host on J&G.
In a montage, it is revealed that the business is a continuous loop: the jewelry made at the factory is shipped to the United States, where scam artists sell it to senior citizens, who give them as gifts to relatives.
Nicholson also noted the similarity of Stan's phone call to J&G, in which he angrily urges the host to kill himself, to the "Marketing and Advertising" bit from comedian Bill Hicks' 1997 album Arizona Bay.
