'Engagement' takes over Thursday slot

CBS will replace its now-defunct Thursday comedy “How to Be a Gentleman” with its workhorse “Rules of Engagement.”

As of Oct. 20, the veteran half-hour starring David Spade and Patrick Warburton will trade its Saturday 8 p.m. timeslot with rookie “Gentleman,” which failed to hang on to its plum Thursday 8 p.m. lead-in, “The Big Bang Theory.”

“Gentleman” will move to Saturday on Oct. 15 for its last few airings; production on the CBS TV Studios laffer has been shut down.

“Gentleman’s” fate was sealed when last week’s episode sank to 7.6 million total viewers, a precipitous plunge from the 13.9 million who tuned in “Big Bang.”

While not the cancellation some may have expected after two weak ratings perfs, moving “Gentleman” out of the Thursday 8:30 p.m. berth is the first rejiggering CBS has done to its fall schedule, which has otherwise seen solid starts from Monday laffer “2 Broke Girls” and Tuesday drama “Unforgettable.”

The decision to call up “Rules” from the Siberia of its Saturday timeslot comes as no surprise. The Sony Pictures TV sitcom has been a sturdy utility player for CBS for most of its six seasons. CBS’ decision to program it on Saturdays this season was always seen as a place-holder until a vacancy opened up on another night.
