Is it really goin to end?!?

Do you really think it could go on forever. Do you really want what happened to the Simpsons-which is totally not funny anymore. I think if you run out of ideas and just end up making a social commentary on the culture of the moment (eg. Jersey Shore) it isn't funny or original. Better to let things die on a good note- rather to struggle and pathetically grasp to the railing.
