Conjoined rattlesnakes! Complete with mildly disturbing video!
The snakes will be surgically separated despite Mother Nature's clear intent to keep them superglued together at the head, since they apparently can't exactly agree on which direction to slither or what to bite, and will be live out their days in luxury at the Desert Museum in Tucson. Where they will never have to share snacks again. Stop by and say hi, hi when you get the chance.
