That "MILF Island" episode of 30 Rock everyone was talking about Friday? In which 20 hot moms square off in front of 50 eighth-grade boys at "Erection Cove?" It aired during NBC's "Family Hour," in which the whole family is supposed to be able to gather in front of the TV together. NBC executive Ben Silverman re-launched the concept just 10 days ago. Anyone who took the man at his word — and hopefully few people did — either had a very awkward night or has a very interesting family. Now NBC is trying to rewrite what it meant by "family hour." Here's network exec Mitch Metcalf in tomorrow's Times:

Mr. Metcalf said that the family-hour designation should be seen as offering “direction for program development,” not “black-and-white expectations” for the audience.

“It was not to be construed as a return to a strictly defined family hour,” he said, featuring wholesome shows like “Little House on the Prairie,” a hit on NBC in the late 1970s and early ’80s.

Below, a brief reminder of what NBC's not-so-"strictly-defined" family hour now looks like. It was kind of bizarre to slot 30 Rock into a family hour to begin with.
