I thought this would be a very interesting thread to start. As I heard this story recently for the third time and it still had the same effect. So add your own stories please.
The story: "A friend of a friend of a friend room mate in college in Cork/Dublin used to have pet snake. A normal snake fed mice, but the nly difference was that the she would let the snake sleep at the bottom of her bed at night. Like a dog coiled up at her feet on top of her duvet But gradually the snake began to starve its self wouldn't eat anything. Then the snake began sleeping parallel to its owner, stretching itself as far as possible each night. For a few weeks the snake continued this behavour, eventually the owner decided to take her pet snake to the vet. It turned out that the 'pet'snake was starving itself for the big meal and was trying to decide when it would be big/long enough to eat its big meal. The snakes owner!"
