SERIES PREMIERE: Based on a recurring feature from Ellen DeGeneres’ talk show, this series is part Candid Camera and part Punk’d. On her talk show, DeGeneres would sit back in the studio, watching on hidden cameras and instructing her co-conspirator, who was listening in a tiny earpiece, to do and say whatever Ellen suggested. The humor stems both from how the orders are carried out and how the clueless “mark” witnessing all this reacts. And now it’s a series, with The Goldbergs star Wendi McLendon-Covey taking over the Ellen role, and with celebrities as her co-conspirators. In tonight’s premiere, the earpiece-equipped good sports include Sarah Hyland from Modern Family and American Idol alumni Randy Jackson.
