Futurama Episodes

Election day is drawing nearer, but Fry and Bender are unmoved by politics. While Leela convinces Fry to register to vote, Bender sees something on TV that does interest him. He learns that a titanium mine collapsed, causing the price of titanium to increase. Bender sees this as an opportunity to make some cash by selling his body, firmly convinced that life without a body is worth it for the money. He visits the Head Museum but starts to miss his body when Nixon reminisces about his own. Determined to reunite with his body, Bender sets out to buy it back. He is startled to discover that it has already been sold. He’s even more surprised when he sees Nixon on TV announcing his candidacy, using Bender’s body as his own!
wikipedia.org summary:
After the price of titanium skyrockets, Bender pawns his titanium-rich body. Now nothing more than a head, Bender begins to live glamorously until he meets the head of former president Richard Nixon, who tells him that life as a head is actually depressing. Bender decides to buy his body back, only to find it has already been bought by Nixon so that he may participate in the current election race for President of Earth. Fry, Leela, and Bender confront Nixon over Bender’s body, and Nixon rants about his devious future plans for Earth, which Bender records and uses to blackmail Nixon into giving his body back. The three believe they have defeated Nixon, but because Leela forgot to vote, Nixon wins by a single vote thanks to acquiring a new, giant war robot’s body.
