Call it the revenge of the killer pork chops if you will.  The porcine enemies of the popular video game "Angry Birds" now have their own app called "Bad Piggies".  Game maker Rovio says, according to MetroSource,  "There's a lot of empathy towards the lovable enemies from the Angry Birds games and we've been constantly asked what about the pigs' side of the story".  The new app will let you trade places and make like a pig instead of an angry bird.  Oink!
