A flock of "counting sheep" find themselves out of a job in a new TV campaign from Serta. The clay animation in the commercials is the work of the U.K.'s Aardman Studios, of "Wallace & Gromit" and "Chicken Run" fame. Doner
, Southfield, Mich., created the advertising, in which the sheep show up for their usual night shift only to learn they're no longer needed by their clients, who have instead bought a restful Serta mattress. The spots are tagged "Serta. We make the world's best mattress." Copywriter: John Parlato. Art director: Kenny Sink.
