Plot:

The family discovers that Snot made a list of how hot the family is. To protect his top ranking, Stan decides he needs to make a magazine for men. To finance it, he cannot get a loan from a bank but finds that Barry's grandmother left him a large inheritance and talks him into financing it. But when he needs a larger loan, Barry cuts him off but he finds a new investor in Toshi. However, the launch party is a dud when no one shows up. Humiliated, Stan runs out of the launch party is held and is blown away in the wind by his giant coat.

Meanwhile, Roger is depressed because he came in dead last in the list and nearly forgets about his annual sex party. With his confidence so low, he hesitates to participate and finds his guests are primarily interested only in the sex. As a result, he swears off sex and finds a kindred spirit in Elizabeth Hadley, resulting in a sexless marriage. However, the thrill of domestic life runs out quickly. To make matters worse, Roger discovers that Tuttle has taken over his sex party and Elizabeth is participating. Her betrayal triggers Roger to become a creature known as the Grounch, and vows to destroy sex for everyone. After stealing all their sex goods, he awaits to hear them lamenting but finds they are still enjoying sex. He realizes that it's all about feeling sexy inside so he goes and joins the party, reverting to his normal self in the process.
