I have had about 8 different people tell me the story about "Someone they know" who had a pet snake and let the snake lie in bed with them. The snake then started always lying out straight instead of curled up. So they took it to the Vet and the vet told them the snake was preparing itself to eat them.
Now when I hear someone about to start the story I just save them the bother and finish it for them.
