Guess there isn’t a South Park-style rivalry between Family Guy and The Simpsons after all. Seth MacFarlane, creator, executive producer and voice actor of Family Guy, American Dad and The Cleveland Show, will lend his voice to his network-mates The Simpsons for the show’s season finale.

MacFarlane voices a charming married man whom Marge (Julie Kavner) inadvertently meets on a swingers’ website and – obviously – shenanigans ensue. Mistaking a swinging Ashley Madison-type website for a Dolly Madison-type cupcake site, Ben (MacFarlane) pursues Marge after they learn they share a love for a Downton Abbey-type TV series, Upton Rectory.

Also in the season finale, Homer (Dan Castellaneta), Moe (Hank Azaria), Lenny (Harry Shearer) and Carl (Azaria) win $200,000 in the Springfield Lottery, but when Carl takes off to Iceland – his homeland – with all the winnings, the guys embark on a Nordic adventure to get the cash back.

The hourlong season finale airs Sunday, May 19 at 8 PM ET/PT on FOX.

Writer Sydney Bucksbaum likes to think her hobby of watching insane amounts of TV isn't an obsession... it's not an obsession, okay, so just drop it! As the resident CW-lover on the staff, she truly believes her Clark Kent/Dean Winchester/Damon Salvatore/Lucas Scott/Oliver Queen/Chuck Bass/Seymour Birkhoff/Wade Kinsella/Vincent Keller/Micah Barnes is out there somewhere, waiting for her, in real life (just go with it). After graduating from Northwestern University with a degree in journalism, Sydney has made it her mission to campaign for more shirtless scenes for her favorite CW hunks. You're welcome.
