It originally aired on the Fox network in the United States on February 6, 2000. The episode is a parody of the "" episode "Amok Time" and, in part, Cyrano de Bergerac. Amy and Leela drag Fry and Bender to the gym because they are badly out of shape, and Dr. Zoidberg tags along. Fry luxuriates in the coed steam room with Leela and Amy, only to be told that it's the women's steam room. Leela and Amy make fun of Fry's package, and what poor women in the 20th century had to put up with before genetic engineering. Meanwhile, Zoidberg is behaving erratically and aggressively, and even displays his head fin. He runs beserk through the gym. Back at the laboratory, Professor Farnsworth examines a restrained Zoidberg, and determines that it is mating season for Zoidberg's species. The crew flies to Zoidberg's home planet, Decapod 10,arriving 19 hours before the mating frenzy. After a short tour of his "old scuttling grounds", and the stadium where the ceremony of Claw-Plach takes polace, Zoidberg sets up a mound on the beach and begins trying to attract a mate. He is rejected by numerous Decapodian women, especially Edna, an old high school classmate and former crush, leaving him very depressed, as all the other males except him have attracted mates. Fry begins teaching Zoidberg how to win Edna's heart using human romance techniques. Zoidberg struggles to understand how this could work but he eventually gets the idea, and, using his new-found techniques, successfully woos Edna to go on a date. While at a restaurant, Leela reveals to Edna that Fry is responsible for the change in Zoidberg, and the words he is using.. Under the pretext of discussing Zoidberg, Edna invites Fry to her apartment and begins an unsuccessful attempt at seducing him, pinning him down. Zoidberg walks in, witnesses this, and challenges Fry to Claw-Plach, a ritual fight to the death. In the Claw-Plach arena, Fry is about to defeat Zoidberg, but cannot bring himself to kill his friend. A still incensed Zoidberg cuts Fry's arm off with his claw to teach him a lesson, prompting an astounded Fry to retaliate, proceeding to beat Zoidberg with his severed arm.
