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.
