Forgive me, Simpsons, but I don't watch you as often as I used to. I'm not sure when it happened, but at some point, watching The Simpsons slipped from an every-week ritual to catch as catch can.

I'm sure I'm not unusual in that respect. I'm sure there are people who were with The Simpsons from those very first shaky frames, who saw them adopt No. 9 and laughed at Homer botching Christmas songs on the closing credits, and faithfully watched for several years, maybe even a decade before they dropped off.

But one of the best things about the show is, you can always come back. The Simpsons never forget. Yesterday's episode and the 20th Anniversary Special that followed was a nice reminder of that. The episode wasn't the funniest I've seen, but I did realize there has never been an episode of the show that wasn't worth at least a few laughs.
