Ratings: Parks and Recreation Flat in Return; Grey's, Scandal Improve

Parks and Recreation returned after a month off in a new timeslot to the same numbers.
Now in the post-Office berth, the NBC comedy drew 3.5 million viewers and a 1.8 rating in the adults 18-to-49 demographic Thursday, on par with its last new episode in March, when it aired at 8:30/7:30c. The Office (4.3 million, 2.2) was also steady, while 30 Rock (3.2 million, 1.5) rose, and Community (2.9 million, 1.3) and Awake (2.7 million, 0.8) dropped to series lows in the demo.
Idol: Who went home?
Fox won the night with American Idol (14.6 million, 3.9) and Touch (7.3 million, 2.1), both of which fell to series lows.
ABC placed second, thanks to small improvements by Grey's Anatomy (9.7 million, 3.2), which posted a 10-week high, and Scandal  (7.4 million, 2.1). Missing (7.1 million, 1.3) hit an all-time low.
Also hitting a series low: Rules of Engagement (7.7 million, 2.2), which was CBS' only original of the night.
