We used to have a Rock Python, back in the days of the large CRT screens that belted out 1KW of heat, the snake would always head to the TV whenever it heard it was on and quietly curl up on top.
We lived in a shared house, when mates came back after the pub on a Saturday night to watch the Hammer House of Horror film 9 of the 10 people in the room knew all about the snake.
Invariably, one person did not, and it was always worth watching whist they tried to figure out :
A) Who was pulling the string to make it appear the rubber snake was moving across the room
B) There is a 2 meter snake heading for the TV, I can see it, how come no one else can
