All of the characters interact amazingly. The humor exceeds any of which either show has produced before due to the perfect combination of both shows. As per usual Stewie is just hilarious. Peter and Homer stood together just makes me cry of laughter. They are both similar characters and the combination of stupidity and family guy's profanity is hilarious. Each show on a stand alone manages to make me laugh. Even though the Simpsons has a low day time television age rating but now because of the fact that the characters are technically in Family guy's show it means we can see a more adult version of the Simpsons and oh my lord it is just brilliant. After seeing this i really hope there is more Simpsons/Family guy episodes because the one we have is just brilliant.
