I still watch the show, but like a lot of longtime fans, I think that things went off the rails after season nine or ten. At the same time, though, I can’t imagine a world without The Simpsons.
I stumbled across this Mental Floss post of some of the coolest Easter eggs hidden within the show. One points to something Paul McCartney did when he guest-voiced “Lisa the Vegetarian” from season five. At one point Macca says “In fact, if you play ‘Maybe I’m Amazed’ backwards, you’ll find a recipe for a ripping lentil soup.”
