Though her multiple SNL appearances as Sarah Palin have certainly boosted Tina Fey's cultural cachet, true Fey nerds can have their thirst quenched by only one thing: new 30 Rock! NBC has cruelly delayed the third season premiere until November 6 (correction: November 6 is actually the date of the network-teased Oprah episode — October 30 will see the somewhat less-buzzworthy, Megan Mullally-guesting premiere), but the network parceled out a thirty-second morsel of the new season last night.Naturally, the blurb went heavy on guest stars like Jennifer Aniston and Steve Martin (gotta shore up those ratings!) but any new footage of the Emmy-honored Liz Lemon and Jack Donaghy sets our mindgrapes a-racin', no matter how brief. In a cold, show-vanquishing fall landscape dotted with shows like Knight Rider and Kath & Kim, can 30 Rock possibly come fast enough? Save us, Liz Lemon! You're our only hope! [NBC]
