Because both Family Guy and The Simpsons share a mutual appreciation that Family Guy could only dream of sharing with South Park, creator Seth MacFarlane has signed on to guest star in an upcoming episode of Fox’s landmark show. Add this, then, to the ever-expanding list of upcoming things that Seth MacFarlane will do, a list which includes hosting the Oscars and putting together a Family Guy movie.

The episode, titled “Dangers on a Train,” is set to focus on Marge, who accidentally signs up to a website for people wishing to have affairs. There she meets Ben (MacFarlane), who sets his sights on her after they bond over a Downton Abbey-like TV series called Upton Rectory. These events will, of course, drive another fork between Homer and Marge – a fork that will be returned to the cutlery drawer after 22 minutes.

Al Jean, legendary Simpsons producer, said: “A lot of him trying to go after her is over the phone, so it’s a perfect part for someone with his voice.” He also revealed that MacFarlane croons “The Way You Look Tonight” in the episode, because Seth MacFarlane can sing and therefore must.

So, yes, Sunday night on Fox is now Seth MacFarlane night, though years since Family Guy earned a proper laugh, a decade after The Simpsons was funny, and the fact that The Cleveland Show was never something to be amused by, it’s hard to make that sound like a good thing.
