The new Showtime series Shameless, whose sneak preview after the season finale of Dexter has already given us the nude debut of operatic eyeful Emily Rossum, is going to be pouring on the sex, Showtime style, over the course of the season.

Following the tradition of movies like Weekend with the Babysitter, The Babysitter, and The Babysitters (featuring Sam Waterston's daughter Katherine's luscious melons), Shameless is going to show feature Joan Cusack in a sex scene with her own real-life babysitter, William H. Macy.

"I've known Joan for a long, long time," recalls Macy. "I actually babysat Joan Cusack. I started acting in Chicago, and I knew her dad. Joan's mom still talks about a set of bookshelves that I built that are right inside their front door."

Now Mrs. Cusack is going to be talking about another kind of wood Macy gave her daughter.
