Lemon Party! Looks like Tina Fey's second, third, fourth, and fifth jobs this year have paid off, as 30 Rock premiered last night to the biggest numbers in the show's history. THR says the sitcom lured 8.5 million viewers and a 4.1 18-49 rating, up 21% from its premiere last year. We're a little confounded by the fact that Rock still lost 800,000 viewers of The Office — what do you people need, every character on the show to couple up? A premature guest stint from Steve Carell? Prolonged sexual tension between Frank and Cirie (actually, that one we could live with)? [THR]
