The Prince and the Product
Fry, Leela, and Bender deliver a package to a planet where Leela falls in love with the Prince, saddening Fry. When the King forbids them to wed, Fry takes offence and challenges the King to a duel. Leela takes Fry's place, but discovers too late that her opponent was the Prince whom she kills. Throughout the episode, it continues to cut to commercial where it depicts the Planet Express Crew as different toys. First as wind-up toys, then as cars, and finally as rubber duckies and wobbles. Back to the "main plot", Leela reveals that she was under a "science spell" and is still in love with Fry.
