ehh...they've been cranking it for a long time and they seem 2 come up w/ good stuff still...and i doubt they'd kill homer off. Yes...south park is great...and they did survive after killing of kenny...lol...but....honestly i dont know why i guess simply because simpsons has been around for SOO long and hasn't quite gotten old yet. We'll see...all we can do is speculate right now...eventually one of them will die...hopefully they both stick around for a while.
