Al Jean: (Describing why The Simpsons never grow) I never want people to go: "Oh, this is the episode that changed everything!"
Al Jean: (Describing working on The Simpsons) It's the greatest job in the world...
Al Jean: People tell me all the time, "Oh, you should be a voice, you have a cartoon voice!" I'm like, "What does that mean?!"
Jean:(Describing The Simpsons Movie) I'd say in one sentence it's that a man should listen to his wife.
Jean:(talking about how to keep The Simpsons going) I'd say for Futurama, four or five years is pretty good by TV standards. For this show I think there's three things. The fact that the original universe created by Matt and Jim Brooks and Sam Simon are really rich, there's just so many great characters that we can do a different kind of episode every week without wearing thin. The fact that the characters don't age, you don't watch the show and see it's radically different than it was ten years ago. A good episode from season fourteen will stand up to a good episode from season four. And everyone takes it real seriously. The writers, the cast, we work hard trying to do what people have grown to love without repeating ourselves.
