Synopsis
Grandma Connolly has her new television installed. Later, the woman sits down in front of it, and strange red lightning reaches out from the television towards her. As she looks back at the screen, the lightning retracts back into the set and dances on the screen. The Grandma presumes that the set is broken, so she proceeds to hit it with her hands. The lightning shoots towards her face and she shouts for help. The television then shows a trailer for the upcoming coronation of Queen Elizabeth II...
