Proposition Infinity

"Proposition Infinity" ("Proposition ∞") is the fourth episode in the sixth season of the American animated television series Futurama, and the 92nd episode of the series overall. It originally aired on Comedy Central in the United States on July 8, 2010. In the episode, Amy Wong and Bender fall in love and begin a culturally taboo robosexual relationship. After facing anti-robosexual sentiments from society, they elect to get married and advocate to legalize robosexual marriage through "Proposition Infinity".

The episode was written by Michael Rowe and directed by Crystal Chesney-Thompson. "Proposition Infinity" served as a satire of the controversy over same-sex marriage and California Proposition 8 (generally referred to as "Proposition 8"), which banned same-sex marriage in California in November 2008. The title of the episode is derived from Proposition 8, turning the 8 sideways to create the symbol for infinity (∞), hence "Proposition ∞". Though the episode satirizes arguments for same-sex marriage, it leans favorably toward the idea of allowing same-sex marriage. The theme of the episode revisits the social taboo of robosexual relationships presented in earlier episodes "Space Pilot 3000" and "I Dated a Robot". Openly gay actor George Takei of Star Trek fame, who married his partner in California during the debate over Proposition 8, returns as a guest star in the series.

"Proposition Infinity" received mostly positive reviews from critics. Co-creator David X. Cohen named it as one of his favorite episodes of the sixth season.
