I remember hearing quite a while ago that they would only ever make a simpsons movie when they were going to end the series. Now that one will be out shortly it makes you wonder how long they will go on for. I heard they are doing atleast one more season, but i hope its good, the past few haven't been that great.
I love the old episodes, like the frank grimes episode, or the one where they get trapped in the school, ahh fun times.
