¡Ay caramba! It may soon be time to say good-bye to 'The Simpsons.' Edge of the seat contract negotiations are nothing new for the show, but now Fox has reportedly upped the ante, telling cast and crew to settle or lose their jobs.

According to 'The Wrap,' Fox has said that if no agreement is reached in the ongoing contract dispute the show will be cancelled at the end of the current 23rd season.

And, even if the dispute is settled before tomorrow's deadline, the network will only air one more season of the show.

After 23 years, could 'The Simpsons' be signing off for good?

According to a new report by The Daily Beast, the actors are in a tense contract negotiation with 20th Century Fox. Contract negotiations aren't new for the long-running cartoon comedy, but the report -- which Fox didn't comment on -- says studio executives are insisting the cast accept a 45 percent pay cut or face cancellation after the current season.

Kiefer Sutherland lent his voice to 'The Simpsons' (Sun., 8PM ET on FOX) as a character reminiscent of his Jack Bauer days. Wayne is the new security guard at the nuclear power plant, but he has flashbacks to a much more dangerous past.

One flashback revealed the special CIA training he received, complete with circus strongmen, ferocious animals, Chucky and Kobe Bryant! But, despite his harrowed past and his resistance to befriending people in Springfield, Homer gets under his skin.

And then Homer needs saving when Wayne's past literally comes to town -- though we're not sure how he found it considering Wayne chose Springfield because it isn't on any maps. It was a fun episode, and a fun character for Sutherland. We loved the Korean animation re-enactment, and we're happy to see Nedna going strong!

Facebook co-creator Mark Zuckerberg has already made a guest appearance on 'The Simpsons,' and now the animated comedy is getting ready to spoof the fictionalized version of his life.

Yes, 'The Simpsons' will take on 'The Social Network,' in an episode due to air in 2012 called -- what else? -- 'The D'oh-cial Network.'

'The Sun' reports that 'The Simpsons' homage to Aaron Sorkin's 2010 movie will see Lisa create a social network site in Springfield but give too much credit to everyone else.

And at least one of the movie's stars will be reprising his role in the Springfield version.

'Arrested Development' and 'Superbad' star Michael Cera joins the long and illustrious list of stars who have recorded a guest spot on 'The Simpsons.' And Cera even got to play a potential love interest for Lisa.

'Simpsons' executive producer Al Jean told 'Entertainment Weekly' that Cera provides the voice for Nick, a seemingly gallant boy.

"He starts quoting Hemingway and she says, 'You're not a product of the Springfield public schools, are you?' And he goes, 'No, I come to Springfield for the food and the women.' So he talks a good game."

Sadly for Lisa, first appearances can be deceptive, and she starts to realize that Nick is "less than expected."
