This Thursday in ratings-land:

8 pm/ET
The penultimate Survivor: Fiji put up a typical 13.64 million total viewers, as Ugly Betty (9.38 mil) plunged 1.3 mil. Earl's riotous season-ender (6.6 mil) lost 980K versus last week's Laugh 'N Sniffer. Smallville (3.36 mil) dipped 200K. (Do not get me started on the supersized Office and Scrubs numbers.)

9 pm
With 18.6 million viewers, CSI gave Grey's (19.07 mil, down 1.9 mil) a scare. Speaking of scares, Supernatural (2.85 mil) spooked 310,000 fewer folk. Regarding Grey's, welcome, welcome, welcome, Chyler Leigh as "forward" bar girl. You are a much-needed shot in Derek's arm.

10 pm
While the Shark's away... no one gets to play. Airing in a special time slot, Without a Trace's season finale drew 14.4 million, easily topping ER (9.2 mil, up 1.2 mil). ABC's Traveler sneak peek (8.8. mil) fell short of the Thursday-at-10 debuts of both October Road (14.38 mil) and Men in Trees (11.9 mil).

UPDATE: I just changed the headline because though I didn't research the numbers earlier, I now see the trades noting that Betty hit an all-time low for a fresh eppy, while CSI and Grey's delivered their lowest numbers ever for Thursday originals.
