Well, it's been in the news for the last week - The Simpsons and Family Guy are crossing over for an episode due to air in 2014.
For Family Guy's upcoming 12th season (which will also feature Ashton Kutcher and Peter Dinklage in later episodes), the Griffins will meet their Springfield counterparts with castmembers Dan Castellaneta, Julie Kavner, Nancy Cartwright, Yeardley Smith and Hank Azaria as the Griffins take a roadtrip and end up in Springfield with some alliances and clashes expected with Homer/Peter, Marge/Lois, Bart/Stewie throughout the episode. The episode itself will go by the title of The Simpsons Guy too.
I have to admit, I'm not really sure of this. Both shows aren't as good as they used to be and crossovers don't always work. Plus, I have an urge to fast forward through the Peter/Homer scenes as well. Then again, it might actually be the very thing both shows could do with at the moment but it's hard to deny that it seems more like a publicity stunt for two shows that don't have the impact that they used to though. It's also been confirmed that Cleveland will return to Quahog and a member of the Griffins will die at the end of the upcoming season and be replaced by a new family member too. Is it too much to hope that it's Peter?
