I'm not going to lie, this video is for hardcore Simpsons fans only.  And it's more than safe to consider me one of those.  Watch over 20 years of mouse on cat violence right here.

 

There have been some good shows inside of shows, but Itchy and Scratchy is easily one of my favorites.  It's a long video, but The Simpsons have been on for a long time.  It's crazy to see those really early episode clips, and how different everything was.
