Who voices this alien that Marge reveals to have had a one-night stand with and got impregnated with Maggie?
Treehouse of Horror IX "Treehouse of Horror IX" is the fourth episode in the tenth season of the American animated television series "The Simpsons". It first aired on the Fox network in the United States on October 25, 1998. This is the ninth "Treehouse of Horror" episode, and, like the other "Treehouse of Horror" episodes, contains three self-contained segments: In "Hell Toupée", Homer gets a hair transplant and is possessed by the spirit of an executed criminal; in "Terror of Tiny Toon", Bart and Lisa are trapped in a special, extremely violent episode of "The Itchy & Scratchy Show"; and in "Starship Poopers", Marge reveals that Maggie is the product of a one-night stand with the alien Kang.
Zoidberg Doctor John A. Zoidberg (referred to only by his last name Zoidberg) is a fictional character in the television series "Futurama". He is a Decapodian, a lobster-esque alien who works as the staff doctor for "Planet Express", despite his poor understanding of human physiology and allusions to his questionable credentials. His character parodies the supposed wealth and automatic respect of modern doctors—for example, his incompetence at human medicine makes him extremely poor despite his profession, and he is implied to be frequently homeless when not at work. The Decapod (named after the actual Decapoda order of ten-footed crustaceans) are an extended parody on Yiddish culture—the bigger joke being that shellfish are not kosher. The writing riffs on the marine theme in a playfully absurd way, with just about any marine Arthropoda or Mollusca being implied to be akin to Zoidberg. Zoidberg is voiced by Billy West, who performs the character with a Yiddish-inflected accent inspired by actors George Jessel and Lou Jacobi.
