Can you make an ESL curriculum from "The Simpsons"?

I'm looking for videos to use for advanced conversation ESL, clips that contain regular spoken English, slang, colloquialisms, etc etc.

So far, I've used The Daily Show (audience noise makes it difficult to follow, plus too political); South Park (the World of Warcraft is barely passible). Then I thought maybe the Simpsons. Youtube clips of the Simpons.

Here's google video

And metacafe.com

ANy other suggestions? Please comment below...
