Even just typing that makes me realize how many fucking great episodes the series had, those were just off of the top of my head.
I probably don't consider it the best overall, but I think that the ending credits scene of Mother Simpson was genuinely one of the most touching moments to air on TV. Feels like it's at least worth mentioning.
