Some chief executive officers like to surround themselves with subordinates who won't talk back, but few go as far as Pat McGovern, CEO of CW Communications Inc. McGovern keeps a life-size male mannequin seated in a chair in his office. He talks to the mannequin when he needs to rehearse a presentation, or simply to get something off his chest. And, since the mannequin is visible through his office window, it keeps outsiders from dropping in for casual conversation. "It's an offbeat way to manage my time more effectively," says McGovern. "And this may sound odd, but the mannequin even gives me a sense of companionship."
