I'd go with anything from "Homer the Heretic'', but if I had to pick a favorite I'd go with:

A very promising pilot to The Simspons. Hopefully Fox won't cancel it.

I just rewatched ''Itchy and Scratchy: The Movie'' not too long ago. The flash-forward scene at the end of that episode is now what I consider canon. It's heartwarming and funny, unlike this mess of an episode.
