Biffo the Ratman: rats the silent assassins

The soft drink firm had sugar and where there is sugar there will be a multitude of rats. Standing between the rats inundating the factory was Biffo. He knew more about rats than all the experts put together. With traps and poison he kept the numbers down. But in time they became immune to the poison and learned how to trigger the traps without getting trapped. He could see them one day being a bigger problem than any pest known to man. Hopefully not in his lifetime but eventually the 7 billion rats [ one for every man woman and child] will succeed and rule without mercy
