Grey's Anatomy was No. 2 with 13.54 million viewers (a 12 percent drop from its last fresh outing), but of course topped the demos.

Eleventh Hour held onto the top spot with 11.8 million viewers, dipping 370K week-to-week. A cavalcade of returning faves helped ER surge 22 percent to hit 10.7 mil, and place No. 1 in the demos. Did it dawn on anyone else that Seattle plays home to both McDreamy and the McDreamyER Doug Ross? Kinda makes up for all the rain, doesn't it, ladies?

Private Practice came in third with 9.07 mil, plummeting 20 percent.
