'The Simpsons' Green Episode: Family Goes Off The Grid (VIDEO)

This Sunday's Earth Day-related episode of The Simpsons was an eco-travaganza. Homer gets totally fed up with the family's overuse of electricity and decides the family needs to use alternative energy instead. He quickly gets talked into buying a windmill for the house by some Danes. Hilarity ensues.

Another theme of the episode is Lisa trying to save a beached whale -- the writers even manage to throw in some informative information about the problem of shark finning -- challenging the myth that sharks are dangerous creatures to be fearful of. With guest appearances by Hank Azaria and Harry Shearer, this episode is a must-watch.
