Or at least any that you can remember in the 20 plus years the show has been on the air?

In the style of the James Cameron film, Avatar, The Simpsons get inside a transporter and are seen as members of the Na'vi tribe. Na'vi Bart tames a wild flying couch before the family sits down in front of the TV wearing blue and red 3D glasses. -"The Fool Monty"

Tonight's episode, where Marge murders Homer and Bart gets blamed.

My favorite one is when the family jumps on the couch and the giant foot stomps on them. :lol:
