The episode was written by Ken Keeler and directed by Bret Haaland, and it guest stars Dan Castellaneta, who reprises his role as the Robot Devil.
Set in a retro-futuristic 31st century, the series follows the adventures of the employees of Planet Express, an interplanetary delivery company.
In this episode, Fry makes a deal to swap hands with the Robot Devil so he can better play the holophonor, an instrument he believes can help him express his true feelings for Leela.
After a disastrous recital, Bender recommends Fry enlist the help of the Robot Devil to improve his holophonor skills.
After the opera insults the Robot Devil, he interrupts and demands that Fry give him back his hands.
Because Fry can now no longer play so expertly, the entire audience storms out sans the sympathetic Leela, who requests that he finish as she wants to know how "it" ends.
To a simplistic yet sweet bansuri tune, the created Fry and Leela kiss and then walk into the distance hand-in-hand.
[5] Due to the ending of the series and the loss of John Ritter, Katey Sagal's co-star on 8 Simple Rules for Dating My Teenage Daughter, there was difficulty on Sagal's part in recording the final line of the episode, in which Leela says to Fry: "I want to hear how it ends".
[5] In keeping with the episode's focus on classical music (opera in particular), the plot is loosely based on the story of Faust.
[6] The Holophonor was inspired by the Visi-Sonor, an instrument played by the Mule in Isaac Asimov's Foundation and Empire.
