Sean

Sean is one of Leela's ex-boyfriends who never made an appearance in the show or one of the comics until "Fry and Leela's Big Fling". Leela has, however, mentioned him several times before this. He is known to be uneducated, unambitious, pasty and hunched, but with an incredible, beautiful creative soul, and musical talent. Sean is now married to Darlene, a girl he met at the 99c store.

Trivia

 * Sean had the same reed in his sax for 20 years before Fry broke it.
 * In, David X. Cohen seems to say that he just looked up Sean, possibly referring to this wiki.
