|"Why Must I Be a Crustacean in Love?" (2ACV05)
The Decapodian Emperor was the Emperor of Decapod 10, until his death in the Mating Frenzy of 3001. This is interesting, since the Emperor is supposed to remain celibate as to carry on the crazy traditions of his people. It is possible, that he was just unreasonably horny, and Edna was simply just that sexually attractive to a Decapodian.
Decapodian Emperor: It is settled! Fry and Zoidberg will fight to the death for the claw of the beautiful Edna.
Fry: But I don't want her.
Decapodian Emperor: Once invoked the sacred tradition of Claw-Plach can not be taken back. It's a recent tradition, only 18 years old, but a traditional nonetheless.
Decapodian Emperor: Listen, lady, as you can plainly see I'm a highly desirable male, groaning with jelly. Yet I embrace a life of celibacy in order to uphold our crazy traditions. One of your friends must die.
