20. Who Shot Mr Burns (Parts One & Two) (S6/7)
A unique two-parter in which the Simpsons – and the audience – have to work out who shot Mr Burns. The result is simultaneously a legitimately great TV event and a parody of one.
19. Homer The Heretic (S4)
Homer skips church, causing Marge to worry that he is losing his faith. A spot-on mix of belly laughs, insightful satire and heart. Plus, God steals the show (it’s not often you can say that).
18. Brother From Another Series (S8)
The second best Sideshow Bob episode brilliantly reunites Frasier‘s Kelsey Grammer and David Hyde Pierce. Even if you don’t get that connection, it’s great to see Bob on the side of good.
17. Bart’s Girlfriend (S6)
Bart falls for a girl (voiced by Meryl Streep) who’s even worse than him. Like all great Bart episodes, it shows his innate goodness and Jessica Lovejoy is one of the best one-off characters.
16. The Mysterious Voyage of Homer Simpson (S8)
Homer hallucinates a space coyote who advises him to find his true soul mate. Only this show can get a touching story about Homer and Marge’s marriage out of that gloriously wacky concept.
