Me and a lot of Simpsons fans have waited eagerly for this new episode. This episode is about discovering for Marge and as Lisa says "you are just like Christopher Columbus, you discoverd something millions knew about already" A great episode, Homer once again shows his love for Lisa by sacrificing himself and in the end it turns out well in the end. We find the Simpson's enjoying internet again as we seen when Homer was Mr X and revealed secrets about the community. This time its Barts and Marges time and they meet all the normal people in Springfield trough a online mulit player game. And in a documentary Lisa is watching we once again find the song Barber' Adigo for strings. A great episode and now we look forward to next weeks episode!
