Seth MacFarlane 'Simpsons' Episode to Air as Season 24 Finale
Seth MacFarlane is adding one more voice to Fox, and it's happening earlier than expected.
MacFarlane, who created and provides voices for the network's "Family Guy," "American Dad" and "The Cleveland Show," will guest-voice the Season 24 finale of "The Simpsons," airing May 19.
This will mark MacFarlane's first time providing a voice for "The Simpsons." The MacFarlane episode was originally intended to air next season but was moved up to this year's finale by the producers.
In the episode -- which is dubbed "Dangers on a Train," and will be the second part of an hour-long season finale -- MacFarlane will play Ben, a charming married man who meets series matriarch Marge Simpson after she inadvertently signs up for a swingers' website.
Marge ends up in the world of online swingers after mistaking an Ashley Madison-type website for a Dolly Madison-esque site about cupcakes and develops a bond with Ben after discovering that they are both fans of a "Downton Abbey"-type series titled "Upton Rectory."
Comedian Lisa Lampinelli will voice Ben's wife.
The first part of the finale, "The Saga of Carl," will find Homer, Lenny, Moe and Carl winning $200,000 in the Springfield Lottery. Complications develop when Carl takes off to his native Iceland with all the winnings.
