I Sing the Body Electric: Teleplay (The Twilight Zone) by Ray Bradbury Following the untimely death of their mother, a family decides to buy an electric grandmother in order to help around the house and serve as a nanny for the three children. Thrilled at

 the idea, Tom, Timothy, and Agatha go with their father to the Fantoccini company showroom in order to custom build their new grandmother. The children take turns selecting her parts, the color of her eyes, even the tone of her voice. Weeks later, a mysterious package arrives, a sarcophagus containing their factory-fresh electric grandmother. At the turn of a key, she springs to life and quickly becomes an essential part of the family. Tom, Timothy, and father immediately begin to love her, but Agatha remains distant, untrusting. It slowly becomes clear that Agatha does not believe that grandmother will always be there for them; she is afraid that she’ll leave them, just as their mother did when she died. One day, Agatha runs from the house in tears, straight into traffic. In a flash, the grandmother pushes her to safety, only to be hit by the car herself. Agatha cries, but finds herself comforted by the grandmother, unscathed by the accident. The grandmother insists that she will never leave her, and that not even death could separate them. Agatha realizes that the grandmother is the only one who can keep that promise, and finally opens up to her.
