Futurama season 5 episode 12
Episode title: Spanish Fry
Fry is abducted by aliens, who harvest his nose as an aphrodisiac. The crew traces Fry's missing nose to Lrrr, leader of the Omicronians, who decides that Fry's "lower horn" would be a much better aphrodisiac to jump start his stagnant marriage with Ndnd.
