A part in an episode I saw recently that made me guffaw:
(Brainstorming things to do to save money)
Bart: I'll take up smoking and give that up.
Homer: Good for you son, Giving up smoking is one of the hardest things you'll ever have to do. Have a dollar.
Lisa: But he didn't actually do anything!
Homer: Didn't he, Lis? Didn't he?
A classic Simpsons moment.
I saw another new-ish episode the other day (may have been new, or no more than a year or two old, as it was in widescreen).
You know you're in for another shitty episode when the couch gag is Avatar. Nothing quite says cutting edge originality like the millionth direct copy of Avatar that doesn't actually contain a joke other than "we're copying something topical, so thus we think we're funny".
Then the originality continued by mocking Fox, then having every network come up with a fake news story by spreading a virus for reasons that aren't actually explained other than some vague empty idea of "media is evil lololol".
Then it turns into a Mr Burns episode, where he takes all of the vaccine, boiling down his character down to the one dimensional attributes of "I'm old and selfish" yet again. Then he gets amnesia in one of the most ridiculous sequences ever of flying into the sky and getting hit by a plane and bouncing off some trees. My mind was already sort of wandering by that point.
Then Smithers goes and works for Dick Cheney, with a series of fresh, original political jokes.
Then some more super cartoony crap that made no sense and I barely remember.
Then Mr Burns realizes that hate keeps him alive or some shit. Then he plans to take revenge on the town by covering it with a giant dome, in a reference to the movie. Note: reminding me that the Simpsons movie was ever made is not a good decision.
The episode should have finished at that point, but then they kept going with something else I can't remember.
Give up, guys. You've already destroyed your legacy with more bad seasons than good ones.
