I can say that every Sunday religously I watch the Simpsons. I have been viewing them ever since the Tracy Ullman Show back in 1987. It's a simple cartoon with sometimes very deep humor. That is what trully keeps me watching this show. It never seems to get old because the humor always seems to capture some other topic. I have purchased every season of the Simpsons available. And watching the episodes time after time repeat after repeat I still get a good laugh. It never gets predictable and may be what keeps this show going for another ten years.
