Best Episode Ever!

Actually, I do need some more nominations. I want to have ten choices in the poll, and so far I have one ep with five nominations, two with four, and eight with three, which equals eleven episodes that qualify. Basically, I'm going to need some more nominations so I can have a different combination of top episodes here, so I can start the poll properly.
Well, since no one is nominating anymore, I'll just open up the poll with less than ten episodes.
My top five:

1. Lisa the Vegetarian
2. Sideshow Bob's Last Gleaming
3. 22 Short Films About Springfield
4. The City Of New York vs Homer Simpson
5. Homie The Clown
