30 Rock returned with a third season as part of NBC's 2008 fall schedule, airing immediately after The Office. The show experienced a large ratings and popularity spike this season after Tina Fey's highly praised performance as Sarah Palin on SNL. This is also the season where the show made Primetime Emmy Award history, being nominated for 22 awards. The season consisted of 22 episodes. Oprah Winfrey guest-starred in the second episode, playing herself (actually a drug-induced hallucination of Liz's), as well as Jennifer Aniston playing Liz's ex-roommate. Salma Hayek also appeared for a multiple-episode arc, portraying Jack's new girlfriend, Elisa. Other guest stars this season included John Lithgow, Kerry Butler, Megan Mullally, Peter Dinklage, and Steve Martin. Jon Hamm played Liz's love interest and neighbor for several episodes. Alan Alda appeared in the season's final two episodes as Milton Greene, Jack's biological father. The season finale featured multiple musical guests, including Talib Kweli, Michael McDonald, Norah Jones, Steve Earle, Moby, Clay Aiken, the Beastie Boys, Adam Levine, Mary J. Blige, Elvis Costello, Sheryl Crow, Rhett Miller, Cyndi Lauper, Sara Bareilles, Wyclef Jean, and Rachael Yamagata, performing "Kidney Now!", an organ-donation drive spoof of We Are The World and "Just Stand Up!".
