Favorite Simpsons Episode?

I've been rewatching The Simpsons like crazy lately.. This always happens every once in a while. I realize I haven't seen a Classic episode in a while, and then rewatch the show from it's glory years (Seasons 3-10) like absolute crazy. I've watched most of Season 4 now, some of Season 3, some of Season 7, and began 5 the other day.

In my personal opinion, I think that "Homer's Barbershop Quartet" is my favorite episode. It was everything a Simpsons episode is supposed to be; quirky, funny, charming, and even had a good little song to add into the mix! Other favorites of mine include [i]Mother Simpson[/i], [i]Who shot Mr. Burns[/i], and [i]Duffless[/i]
