Thursday's numbers, at a glance:
* 8 pm/ET
Bones won the hour with 10.76 million total viewers, a gain of 760,000 from its Thursday time-slot premiere. Ugly Betty placed a distant second with 7.27 mil, dropping 270K. NBC's Earl and Kath & Kim both trailed CBS comedy repeats, delivering 6.16 mil (down 340K) and six mil (down 200K), respectively. Smallville slipped 300 thou, to 3.88 mil.
* 9 pm
With CSI taking a siesta, Grey's Anatomy surged 900K to deliver 15.2 million total viewers. While NBC's The Office (8.4 mil) dropped 340K from its last Thursday outing, 30 Rock (6.33 mil, and guest-starring a charming Jon Hamm) dipped only a hair. Supernatural (3.34 mil) slipped 240 thou (but how about that brotherly smackdown?!).
* 10 pm
Goosed by the onset of its multi-episode crossover with Grey's, Private Practice saw 13 million viewers - a 35 percent gain from its last typical outing, and exhibiting none-too-bad audience erosion over the hour. That nifty number also marks a season high and the spin-off's second-largest viewership ever. OK, let's throw this in, too - this week's Private delivered the best-ever retention (86 percent) for a telecast airing after Grey's. Hey, I'm just the messenger, Six Degrees and Notes from the Underbelly.
Trailing an Eleventh Hour repeat, ER (7.3 mil) fell 400K.
