The Simpsons used to be one of the more conservative shows on TV.
I think a lot of people who trashed this show from the start don't realize this. I THOUGHT the Simpsons at the start was going to be what it turned into 10 years ago. Sure there was a lot of silly, irreverent humor back then, but every show ended with a positive conservative message. It was really the show's charm at that time.
My favorite will always be the "stay home from church" moon waffles episode.
