Mc Donald's also uses worms as a filler to their burger and Kentucky Fried Chicken changed their name to KFC because they produced a genetically modified chicken that has 2 sets of thighs and drum sticks and 2 sets of wings per bird, the birds don't have feet or beaks. So they can NOT say its chicken. People thought they didn't want to say the F word in their name "Fried" so it worked out for them until now.
