Alice is sitting in her cubicle. On the other side of the wall, a cell phone makes the noises, "Beep-beep-a-beep-beep-a-beep." Alice thinks, "Every two minutes." Alice looks into the next cubicle and and clenches her teeth at the cell phone lying there. A coworker approaches Alice and asks, "Have you seen my cell phone?" Alice responds, "Was it metallic, noisy and flushable?"
