Crying over spilt milk

Most newspapers carried the story today of supermarkets selling milk from cloned cows. From a comic book/super hero point of view this is just the sort of thing that might lead to the imergence of super villains. People who were mearly mild mannered traffic attendants or call centre staff by day drink this strange milk and develop some sort of evil alter-ego and then find they have a keen sense of smell or something... or maybe it'll just turn your piss green and your balls will shrivel up!!
