David X. Cohen

David X. Cohen is an executive producer, show runner and writer for Futurama. Born David Samuel Cohen, he changed his middle initial in order to register with the Writers' Guild - the Guild has a rule that no two members may have the same name, and there was already "some jerk" registered with the name "David S. Cohen". He chose the "X" because it sounded more science-fictiony.

Biography
He started as a writer on the Simpsons, and collaborated with Matt Groening to develop Futurama.

Work with Futurama
Although usually not credited, he is responsible for "perfecting" most of the scripts for each episode. He also wrote (and sung) the music for Molten Boron, and designed one of the robots in the robot strip club.

The translation of the Alien Language in is: Yak face is a rare Star Wars figure of Saelt-Marae not released in the USA. Mint figures have sold for thousands of dollars. It was added because David X. Cohen owns one.

Voice works
Although David X. Cohen has not officially voiced any characters, he does do a lot of temporary voice work (which can still be heard in some animatics). He has also been told that he has a robotic voice, and because of this he was persuaded to try out for the part of Bender, but claims he couldn't remember how to do his own voice.

Additionally, in the episode "Love's Labours Lost in Space", the voice that announces "This is Vergon Six" is supposedly a heavily digitized David X. Cohen. He also filled in for Billy West for one line in the episode "I Dated a Robot", and in Bender's Game, along with editors Paul D. Calder and Danik Thomas, he voiced the choir that sang the number rolled on the Die of Power.

Cohen appears as his own head in a jar in the episode "Lrrreconcilable Ndndifferences", alongside fellow Futurama crew members Matt Groening, Patrick M. Verrone and Crystal Chesney-Thompson.
