Hedonismbot

Hedonism Bot is a robot who has the concept of hedonism written right into his programming. He is fond of grapes, wine, opera and vomiting, among other things, and apologizes for nothing. His behaviour resembles that of a rich decadent Roman noble of ancient times, and he is a great patron of the opera with his very own box in the Metropolitan House of Opera. He actually ordered Fry to write an opera in which Fry would perform playing the Holophonor. It is unclear what purpose, if any, Hedonism Bot actually serves. He is allegedly built with tax dollars.

In the season three commentary, Matt Groening points out the importance of the name being hedonism bot and not hedonist bot - he is not only hedonist, he is the actual personification of hedonism.

Trivia

 * Hedonism is the philosophy that pleasure is of ultimate importance, the most important pursuit.
 * Hedonismbot is one of the very few robots designed without square pupils. However, there was one moment in The Beast with a Billion Backs when he did have square pupils.
 * Another design flaw arose in The Beast with a Billion Backs when he had a mouth designed similarly to Bender's instead of vertical lines, though it worked the same as usual.
 * Is made of solid gold (although apparently there is some plating to give him different shades of it).
 * Is a member of the League of Robots.
 * He has a semi-recurring valet/possible lover named Djambi.
