Snake tales

A recent Snopes (debunking urban legends) entry talked about snakes - specifically reports where people had woken to find their pet snake in bed with them - but, uncharacteristically, stretched out straight rather than coiled. Other odd behaviour noted - said snake has been off its food for a while. A vet is able to provide the answer - the snake is getting ready for a "large" meal ... and that would be you. The vet knows that because the being in bed next to you is where the snake is measuring you up to see if you'll fit. I know, unlikely story (and False), and that's what Snopes is all about.
