I think the term for the chicken in mcnuggets is "pressed" meat. Which is what's left over at the factory when they ship out the good cuts of meat. Take whatever is left on the floor sweep it up, put it in a press, whala you have a mcnugget. Once when I was at the vet gettin my new dog checked out, he told me how "Pro Plan" dog food rejected the same meat they use for "chicken" at Mc D's. Dogs lick their own asses, but the same food billions of people eat everyday isn't good enough for them.
