*SPOILER*
Ah-hem:
Marge, sick of Homer's snoring and her logical impossibility to sleep, goes to Patty and Selma for the night. There she has a "ladies party", where they exceed a bit with al-key-hol. Seeing on the news that Artie is now the second or third most rich person in Springfield, the sisters convince (well, they do all of the work) Marge to send him an e-mail.
Upon receiving it, Artie decides it's time for him to fulfill his lifelong dream... spending a night with Marge.
So he lands in OFF's garden (

) and offers Marge and Homer 1,000,000$ . At first MArge is obviously not happy with this thing, but they need cash for Homers nose surgery so she accepts, having made clear the night does not involve "funny things".
So, Artie prepares things to recreate perfectly the same night as the one of the Prom of years before. Marge stays at the game, even because Artie seems to be really change. But he isn't and during the dance he forcibly kisses Marge. Homer (hidden on the ceiling) sees the scene and misunderstands, believing that Marge did it willingly. He runs away with an hilarious ref to "back to the future"

. Marge slaps Artie and runs away too, but she comes home too late and finds a tape where Homer says he's going away.
Gah, this is going long, so i guess alkll that interested you was up here. I'll cut off a bit the ending

Then, with the help of Artie, she manages to find Homer and brings him to safety before something very bad happens (Homer went to work with Carl at a petroil extraction site).
Artie and Marge says goodbye each other forever ( ? ), and Artie solves Homers snoring problem in a way that would be too hard to describe here
