Just weeks after NBC unveiled its much-touted, Ben Silverman-approved "family hour"—only to reveal their loose definition of "family" to include the holy hot mamas of 30 Rock's fictional (for now, at least) Mothers I'd Like to Fuck Island, and its inlet of pubescent discovery, Erection Cove—comes news that the network would be repositioning the sitcom in the more engorgement-friendly 9:30 slot, effective immediately:

"Rock," which has been airing at 8:30 p.m., will now benefit from having the Peacock's red-hot laffer "The Office" as its lead-in. "Scrubs" will inherit "Rock's" earlier timeslot.

Slot switcheroo is a no-brainer. "Rock" has been renewed for next season and is a key part of NBC's sitcom strategy going forward. "Scrubs," meanwhile, will air its final NBC episode in a few weeks.

Despite the brain-free nature of this schedule switcheroonie, we suspect the move was due at least in part to the increasingly racy nature of 30 Rock's plots— a restrategization prompted when Silverman swung into the writers room to congratulate the team on strong debut ratings, and glimpsed a dry-erase board covered in a grid plotting the next 12 Rock episodes by character and illegal sex-act.
