Ratings: Charlie's Angels and Whitney Plunge, CBS' Gentleman Comes Up Short Vs. $#*!

How to Be a Gentleman might be muttering a few coarse words this morning. Although CBS’ new Thursday comedy debuted to a solid 9 million total viewers and 2.7 demo rating, that nonetheless marks a 30 percent drop from what the infamous $#*! My Dad Says did in the plum aprés-Big Bang Theory 8:30 slot a year ago.

Some of Thursday’s other freshman fare fared similarly. ABC’s Charlie’s Angels (7.15 million viewers/1.5 rating) plunged 29 percent in the demo, while NBC’s Whitney (5.37 mil/2.5) dropped 21 and 24 percent, respectively.

The news was “better” for the rest of the newbie class. The X Factor (11.9 mil/3.8) was down 12 percent in the demo but still led Fox to a nightly win; CBS’ Person of Interest (12.42 mil/2.7) outdrew Grey’s Anatomy in total viewers while slipping 13 percent in the demo; and opposite stiffer competition, NBC’s Prime Suspect (5.55 mil/1.5) fell “just” 17 percent from its debut.

The CW’s The Secret Circle meanwhile held steady at 2.1 mil/0.9.

Thursday’s gainers include the night’s most-watched program, The Big Bang Theory (14.6 mil/4.8), which added to its premiere audience; Community (4.1 mil/1.8), up a few points in both measures; The Vampire Diaries (2.7 mil/1/3), gaining 8 percent; and Parks and Recreation (4.4 mil/2.1), which drew a few new eyeballs.

A few other Thursday notes:

* Grey’s Anatomy, drawing barely 10 million viewers and a 3.5 rating, dropped 15 percent in the demo.

* Though Parks and Rec this week delivered a marginally stronger lead-in, The Office (6.6 mil/3.4) was down double digits. Sorry, Nard Dog.

* At 10 o’clock, The Mentalist (12.7 mil/2.5) dominated in total viewers while Private Practice (7.9 mil/2.8) led the demos — albeit with its lowest-rated season premiere ever.
