The answers—and more questions about 24, Project Runway and more—in the latest TV ratings quiz:
1. If this is Team CoCo's week, why is Team Leno winning? Because last night an especially fat The Biggest Loser led into The Jay Leno Show, thus helping Leno score more all-important young adults than O'Brien's final Tuesday Tonight Show. First time that's happened in a while, per TVbytheNumbers.
2. What makes this season's American Idol look puny? Past season American Idols. Other than that, A.I. is still TV's No. 1 show, with audiences of 29.9 million (last Tuesday), 26.4 million (last Wednesday) and an estimated 26.1 million (last night).
3. What's the bad news, good news for 24? Sunday's eighth-season premiere (11.3 million) was down from last year's opener, but up from last May's finale, Fox said. On Monday night, 24 held steady, even as it ran third among the Team Leno crowd behind CBS' comedies and the booming Bachelor.
4. What's the good news for the CW—and the bad news for Gossip Girl? The debuting Life Unexpected gave the network its biggest 9 p.m., Monday audience in a year (estimated 2.7 million). The 9 p.m, Monday slot is also known as Gossip Girl's usual home.
5. What's the humbling news for every broadcast network show that aired at 8 p.m., Monday? A new episode of Nick's iCarly beat all of them, yes, How I Met Your Mother, included, with a series-record 11.2 million viewers.
6. Human Target: A hit or miss? Too soon to tell. Sunday's debut was solid (10.1 million). Last night's pilot rerun lost most of its Idol lead-in (no shock) and about one-third of its audience from its first half-hour to its last (not encouraging). The show makes its time-slot debut tonight.
7. Does Avatar ever lose? Apparently not. Last weekend's Saturday Night Live, hosted by Avatar star Sigourney Weaver, outrated every major prime-time thing on TV on Saturday, NBC said.
8. What is guaranteed to draw a record-size crowd: (a) Jersey Shore, (b) a fight or (c) a fight on Jersey Shore? Too easy, we know. Yes, fisticuffs galore highlighted a two-hour Jersey Shore block o' fun, which averaged a series high 3.6 million, and topped all cable reality shows in the weekly Nielsen rankings. Suite Life on Deck (4 million) and Leverage (3.7 million) were prime time's top comedy and drama cable series, respectively.
9. Whatever happened to Project Runway? Oh, it premiered before a cable-big 2.9 million, it just got overshadowed by Jersey Shore—not to mention its previous season premiere, which drew 4.2 million only four months ago.
