Plot details follow.
Template:Wikipedia Jimmy Vulmer is upset that Cartman is taking credit, and discusses it with his friends. Craig accurately predicts that the situation will quickly spiral out of control, and that he should just let Cartman have half the credit, whereas Kyle advises Jimmy to stand his ground. He does so, upsetting Cartman, who genuinely believes he helped create the joke. He goes to Kyle for advice on how to "out-Jew" Jimmy, and Kyle says to Cartman that his ego is so big that he subconsciously remembers things incorrectly to make himself more important. This is supplemented by Cartman's flashbacks to the creation of the joke, which become more overblown and ridiculous as the episode goes on, ending with Cartman believing he not only created the joke himself, but slayed a dragon, defeated an army of "Jew-bots", and has powers similar to the Human Torch.
Meanwhile, the joke is so funny that it is brought up by Jimmy Kimmel on his talk show. It is also used by David Letterman and Jay Leno. Carlos Mencia then goes on Conan O'Brien's show claiming credit for the joke. The joke is played on Kanye West, who doesn't get the joke, and attempts to solve it, eventually resorting to brutally torturing and murdering Mencia, who admits that he steals jokes to compensate for not being funny and having no penis.
After Cartman and Jimmy go on The Ellen DeGeneres Show, Jimmy questions Cartman taking credit, shortly before they are attacked by Kanye West. Finally, Cartman lays the blame on Jimmy for trying to write himself into the joke, now thinking that Jimmy's ego was the twisted one. Kanye West has an epiphany and realizes that he is, in fact, a gay fish. He then dresses in an open chested wetsuit and dives into the ocean, while singing a song titled "I'm a Gay Fish", similar to Kanye West's "Heartless", and french kissing a Garibaldi and humping an Atlantic Goliath grouper.
