The Simpsons simply cannot be stopped. Fox just picked up the animated juggernaut for a 23rd season, which means it will hit a huge milestone: its 500th episode. That means there's almost 200 hours of Homer, Bart, and the gang on file (and if you want to get technical, it means you could watch back-to-back episodes for a week straight and never repeat an episode). I've been a casual viewer of the show since its inception, and I have to admit that this year's Treehouse of Horror Twilight spoof reminded me of why the show is still worth watching. If nothing else, I may always root for it just because I remember watching the very first episode with my sister when we were too young to understand that a cartoon could be for adults. What about you — do you still watch The Simpsons?
