I've been thinking for a while about something. I think The Simpsons have a ton of deleted scenes in storage, from way back to season 1. I think they could easily make a couple of episodes using pretty much all deleted scenes. It would save time and money. I think it'd be cool to see a scene made back from the early seasons meshed together with more recent season. Maybe they'd have to make a couple of new scenes to tell the plot or whatever, but most of the deleted scenes are jokes that could be put anywhere.
I wish they'd do it for at least one episode. I think it'd be fun to try to fit different scenes together, like a puzzle, to create a new episode.
