Are there any Simpsons after episodes after Season 8 which you'd call classics?

I can only think of a few:

The Cartridge Family
The Joy of Sect
Treehouse of Horror X
Trilogy of Error

I used to be able to tolerate most episodes up to Season 16, but I've recently started thinking nearly everything after Season 9 is disposable crap. I've rewatched my DVDs of Seasons 10 - 13 and I declare there's nothing worth rewatching, apart from the odd one or two episodes per season that the writers actually put some effort into.
