Fry and Leela's Big Fling (first appearance)
Sean is Leela's ex-boyfriend. While Leela maintains that the break-up was mutual, it is apparent that he dumped her and this fact is explicated when she meets his wife Darlene when Leela and Fry are tricked into visiting a resort which turns out to be a Zoo habitat on the planet Simean 9 just after Sean and Darlene. Sean is a musician who "jazz noodles" on a saxaphone with a 20-year-old reed which Fry damages when trying to start a fight with him. He once recorded a demo and shot a video, but then he lost his phone.
